Review Articles

Depending upon the requirements, several metals and alloyfoams have been developed in the last three decades, e.g.,Al, Al-Si, Al-Mg [1], Cu [7-10], Pb [11], Fe, Steels [12-15], Ni3Al[16], Zn [17], Mg and Ti [18], Al-Cu, MMCs, metallic glassesetc. [1]. Though a large number of new materials have beenprocessed, only Al-foam has seen tremendous developmentand also industrial production. However, seeing the unusualmultifunctional properties of metallic foams, research in thisarea has got a thrust in the recent years in all directionsencompassing material and process development,understanding the mechanism of foam formation, findingavenues for widespread applicability and developingpredictive models for foaming process. It is now widelyaccepted that metal foams have potential of becoming aprime structural material for the next generation ofautomotive and aerospace products, lightweight constructionmaterials and military armour vehicles. Keeping this in view,we have attempted to assess the current status of metalfoam research expectations and the challenges to beovercome prior to its wide industrial acceptability.

Processing of Metal FoamsThe basic aim of foam processing is to incorporate largesize and uniformly distributed gas pores in the metallicmaterials. This can be accomplished by several routes, whichare summarised in figure 2 . This indicates the possibility of

producing metallic foams in two material states: liquid metaland powdered metal. We have summarized it on the basisof gas source used for foams production. The foamingprocess utilizing dissolved gases is due to the precipitationof these gases during solidification of the melt. This processgenerally gives rise to rod-like (known as “lotus structure”)gas pores during directional solidification. The external gassource signifies that the melt is foamed with the help ofinjection of gases such as air, nitrogen or argon directly intothe melt. However, utmost precaution in the gas flow rate,bubble formation frequency and solidification rate isnecessary to effect uniform distribution of pores. The gas

source from a blowing/foaming agent implies theirincorporation in a high viscosity melt to effect foaming ormixing a blowing agent with metal powder followed bycompaction, sintering and foaming. In these processes hightemperature exposure of foaming agent leads to gasformation, which in turn results in expansion of liquid/semi-liquid metal. There are some other processing routes suchas gas entrapment, hollow sphere sintering, slurry or slipcasting, sintering and dissolution technique and by usingpowder around filler materials. All these techniques givevariable performance of the foamed materials in terms ofpore size and size distribution, density and mechanicalproperties.

However, processing of foams poses several difficulties. Thegrowth of cells leads to thinning of liquid metal cell walls,breaking of cells walls and subsequently coalescence ofcells and finally collapse of foam structure. In other words,the complete foaming process is concerned with (1) foaminception or genesis where blowing agent decomposes(2) the evolution and growth of spherical pores (3) furtherfoaming leads to thinning of cell wall and thus change ofpore shape from spherical to polygonal and (4) porecoalescence due to surface tension and gravitational pull.This means the eventful life of foams comprises birth, lifeand death. Our aim is to avoid the death or collapse of foamduring the processing. The main convict for the death of foamis the instability of cell walls under the pressure differencesdue to surface tension of liquid or gravity. The death orcollapse of foam occurs at the peak of third and start of thefourth step [19-20]. This part of the foaming process hasinvolved tremendous challenges before researchers world-wide. The problem of foam stability is generally addressedby utilizing a few methods such as mixing of ceramic particlesin the melt so as to increase the viscosity and cell wallstrength [21], pre-treatment of foaming agent that delays theits decomposition [22], experimenting in microgravityenvironment so that the effect of drainage due to gravity isavoided [19], controlling the process parameter like heatingrate and foaming temperature and prior deformation ofprecursor materials [23].

Industrial ApplicationThe projections of the future fuel crisis, the urgency ofachieving high fuel efficiency along with higher passengersafety in automobile industries and the needs of creatinglight weight construction materials have attractedtremendous consideration for ultralight weight metallicfoams. The implementation of metallic foams in theseindustrial sectors depend to a large extent upon theirmanufacturing cost, the environmental durability and fireretardancy [24]. In general, metallic foams possess a rangeof thermomechanical properties that suggest theirapplications in the areas demanding impact/blastamelioration, heat dissipation, acoustic isolation and heatexchange [25-26]. The projected applications of metallicfoams have already been recognised and a detaileddescription of the requirements of various industrial sectorscan be seen elsewhere [1-5,27]. Recently, National PhysicalLaboratory (UK) made a survey both in industries as well asacademic and research institutions to have an idea of theirpotential expectations from metallic foams. The surveyindicated that the major applications of the metallic foams,

around 32%, in the near future would be directed towardsautomotive and aerospace industries (figure 3 ). In addition

The response from academic and researchinstitutions was 16% in research and development point ofview. As the transport industry has to play a major role in theimplementation of metallic foams, it is essential to know thereasons why it is beneficial to apply foams. Figure 4 shows

candidates to absorb large amount of mechanical energy;therefore, they can also be used as impact energy abosorber.The properties of damping vibrations and sound absorptioncould be well exploited. However, a metal foam can be analternative option compared to other engineering solutionsif two or more of these properties are exploited together.Multifunctionality of metal foams can be realised if alightweight structure is capable of reducing noise andabsorbing impact energy in an automobile crash. We haveconsidered to make an attempt to see where we need to usethese foams in a car. For this purpose we should have anidea of the frequent accidental possibility in different parts ofa car. We also know that foams in transport industries arebasically needed for weight saving, impact absorbing andthermal insulation. Figure 5 shows a sample car (designed

The aim of the development was to separate the two stepsof foaming and shaping of components so as to reduce thecost by continuous production route. The process involvesmaking small volume foamable precursor (similar topowdered metal processing) and foaming them in acontinuous manner on a conveyor belt furnace. The stack ofspherical foamed elements is further sintered to get acomponent shape. The process gives added advantage ofopen porosity thus decreasing the relative density ofaluminium foam to 0.36 g.cc-1 compared to other processes.The advantage of the process lies in the fact that theproduction process has two main steps that are fullyindependent of each other. They can be carried out at differenttimes, in different locations and by different companies. Dueto the bulk character of APM foam elements, all sub-steps infoam element and part production can be fully automatedwith commercially available equipment.

So far as real application is concerned, bare foam is not atall advisable for a given engineering problem, as the basicrequirement for high stiffness requires sandwich panels withdense face sheets. The German Karmann has developed Alfoam sandwich (AFS) panels [1], which are light weight andstiff (figure 6c) . The sandwich panels can now also be formedin any shape by using APM foam elements discussed above[6]. A picture of the sandwich structure with a cellular corelayer is shown in figure 6d . An example of other application

by Karmann, Germany) with components made of Al foam. Itis indicated in the figure that 67% of in-vehicle injury costincurs when the collision takes place at the front end of thecar and about 22% in-vehicle injury cost constitute duringcollision from the side. This indicates that the front endcollision of a car is most detrimental during an accident andtherefore utilisation of foamed materials in these partsbecomes necessary for the passenger safety. As a result,the imperative should be to use metallic foams in the frontend for crash safety and rear end should be replaced withfoam to reduce the weight. In addition to the automobileindustries metal foams have other potential applicationareas, which include compressor casings, structuralhardware, motorcycle exhausts and frames, support forradar antenna, submarine structures, substitute foraluminium honeycomb structures, instrument housings,sound absorbing linings, acoustic transducers, loudspeakerenclosures, gearbox housings, structural parts forspacecraft, thermal management, cores for casting andvibration damping.

As the cost of metal foams is still prohibitive and restricts itswide industrial acceptability recently, IFAM (Bremen,Germany) has developed APM (Advanced Pore Morphology)process [6] where small volume spherical foam elements,in the size range of 9 to 10 mm are produced (figure 6 a & b) .

is crash absorbers in automobiles. As the safety guidelinesand passenger protection has received increased attention,automobile manufacturers are using novel idea of crash boxto meet new standards [27]. The crash box enhances safetyand minimises repair cost in the event of a collision. Theseare placed between the impact beam and the front rail of thecar (figure 7a) . Recently, a spin off company of Karmann hasdeveloped a novel lifting arm, supporting a repair arm in a

small lorry, made of Al foam sandwich structure. This helpsin increasing the lifting height of the systems keeping thetotal weight of the lorry below a given limit. Out of differentfoaming routes, powder metallurgy technique, however, hasbeen recognised a better way to produced required shape ofcomponent. A foamed part made by this route is shown infigure 7b .

Figure 7: (a) Prototypes of crash absorbers based on Alextrusions with a filling of foam (b) shaped aluminium foampart [24].

The requirements of the above components and theenvisaged application of metallic foams made of differentmetals and alloys have led to the commercial production ofwork specific metallic foams. The products include foamfilled tubes and sections as shown in figure 7 , foamreinforced polymer structures developed by threecollaborating German companies Huebner, SchunkSintermetaltechnique and Siemens for use in tram crashabsorbers. There are several commercial establishmentsthat are engaged in the production of metals foams. A list ofa few of them is given in Table 1 along with their trade nameand products.

Future Prospects and ChallengesThe strength and weight saving by using Al foams arecurrently believed to be insufficient for critical areas ofapplications. Therefore, recently, tremendous efforts aredirected towards steel foam developments which, inprinciple, can have several potential advantages over

aluminium foams such as increased strength and specificstiffness, lower raw material cost, higher melting temperatureand compatibility with steel structures [12-15]. Initialdevelopments in the processing of steel foams have alreadybeen done by conventional powder metallurgical routes, andalso by space holding techniques. However, for thecommercial production of steel foams, we have to go a longway as the high operating temperature and the low viscosityof liquid steels are the major challenges to overcome. Theauthors of this paper are also actively engaged in thedevelopment of steel foams along with the processoptimisation for Al foams.

Similar to the development of steel foams, efforts have beenmade to develop bulk amorphous metal foams (AMF). Theamorphous foams are seen to have promising prospects inapplications such as sporting goods and cellular telephonehousings due to their high strength, high eleastic strain, andhigh wear and corrosion resistance. A high corrosionresistance of AMFs compared to other metallic foams isadvantageous in applications such as filters, electrodes andcatalyst supports [28-30]. So far as applicability in transportindustry is concerned, AMFs may not prove to be a betteroption than metallic foam, despite its very high strength.Stronger foams may be able to mitigate heavy impacts butsimultaneously transmit unacceptably large forces todelicate objects or human beings. Therefore, AMFs may begood for structural applications but not for the transportindustry. The processibility and strength of metallic foamsare determined by the processing temperature and strengthof the parent material e.g. Al-based foams can be easilyfabricated by various processes but have mechanicalproperties limited by those of their base alloys, while foamsmade from stronger crystalline alloys generally requirehigher-temperature and/or more difficult processingmethods. Whereas, amorphous metal foams are easy tofabricate due to their low melting temperature andsuperplastic like flow at higher temperatures [31]. Despite alow processing temperature, the application of such AMFs

above the glass transition temperatures, where toughnessis drastically reduced, the use of AMFs is limited to27-480 0C for an extended period. However, processing ofbulk AMFs is still a challenge due to compositional accurayand cooling rate requirements. A slight deviation incomposition, due to external additives for foaming, may leadto deviation from deep eutectic composition resulting instable crystalline phases. Even if the purity is overcome, thecompatibility of external gas blowing phases or spaceholders and the processing equipment must be ensured torealise amorphous foams. Progress in the identification andunderstanding of new glass-forming systems with still higherrobustness against contaminants and slow cooling, whichis currently the subject of intensive research, should lead toequivalent progress in AMFs [28].

Despite the current developments and future possibilities inprocessing and applications of metallic foams, there areseveral limitations, which has to be considered andaddressed so as to open new avenues for the metallicfoams. The first and the foremost hindrance in the wideapplicability of metallic foams is the cost of production. Thesecond concern is the variability in the materials and thelarge scatter in measured properties [32]. And also, reliabletest methods have to be invented to fully exploit the potentialof these cellular materials. World-wide efforts are being madeto model mechanical behaviour of metallic foams, andresearchers are, to some extent, successful in predictingthe same. However, theoretical and numerical modelsrelated to the processing of metal foams are not available,which could be useful in predicting the effect of processparameters. The developmental process could be madefaster by making process models, otherwise ‘trial and error”would be the only way. The lack of process models is due tothe fact that the mechanism of foaming process is still notfully understood. All these aspects of metallic foamdevelopment has restricted the industries only in niche areas,whereas, prior to undertaking wide spread commercialproduction these challenges have to be overcome. Further,large structures of metallic foams can be built only by joiningbare foams or sandwich structures. However, currently,joining metal foams is a big challenge as the foam structureis difficult to keep the foam morphology intact at the joints.

Concluding RemarksRecent technological advances in the field of metallic foamshave led to the development of a wide range of processingtechniques for the open as well as closed cell morphologies.The processing route has to be decided on the basis of thecost of production, materials properties and the intendedapplications of the final product. However, as the cost ofproduction of a good quality metallic foam is still high,continual innovations are underway so as to draw maximumbenefit by opening newer avenues for a wide range ofindustrial applications. Foams of new classes of materialssuch as high temperature melting materials, superalloys,steels, bulk metallic glasses etc. are seeing tremendousapplication opportunities in the near future. However, the lackof full understanding of the mechanisms of foam formationand theoretical/numerical models inhibits the developmentalprocess to a large extent. A versatile predictive model forprocessing as well as property has become a necessity fora faster growth in this direction as well as innovations inprocessing techniques.

History, Range and ScopeNanotechnology is an umbrella that covers many areas ofresearch dealing with objects that have dimensions up to afew hundreds of nanometers. A nanometer (nm) is a billionthof a meter. Thus, as we make a shift towards the nanoscale,we slowly approach closer to the atomic or molecular scales.Atoms are the building blocks of all matter. Materials areassembled in a multitude of ways to get the final product.The properties of those products depend on the atomicarrangement. If we rearrange the atoms in coal, we can makediamond. If we rearrange the atoms in sand (and add a fewother trace elements), we can make computer chips. Clearly,engineering at the nano level can bring about drasticchanges in properties of the products.

While “nano” has become the buzzword in technology onlyrecently, the idea of nanotechnology is not so new. Way backin 1959, Richard Feynman delivered a classic talk duringthe annual meeting of the American Physical Society, wherehe talked about manipulating and controlling things on asmall scale. He further went on to quote “In the year 2000,when they look back at this age, they will wonder why it wasnot until the year 1960 that anybody began seriously to movein this direction”. The year 2000 has come and gone, and itis obvious that the great scientist’s words ring loudly now,more than ever. Due to his vision, Feynman is often regardedas the first nanotechnology guru.

Nanotechnology in its present form has been ushered in byEric Drexler. The revolution originated by Drexler has nowreached gargantuan proportions with far reachingapplications in a number of diverse fields starting fromelectronics to biotechnology. The scope of this newgeneration technology is immense. It finds applications inthe automotive segment. New electrostatic filters; high powerswitches in ignition devices via field emission principles atsharp tips; new catalysts using highly porous and chemicallyselective surfaces all go a long way in the production offaster, pollution free, efficient and reliable automobiles.Manufacturing systems technology has also been a majorbeneficiary on nanotechnology, with efficientnanoelectromechanical devices providing the basis fordevelopment of nano robots and assemblers, which movemolecule sized particles into precise locations. High densityinterconnections by nanoscale surface-activatedinterconnections are made possible by nanowires. Similarly,the development of nanoscale magnetic materials has atremendous bearing on the development of large scalememory storage devices. Without these, the Moore’s lawwould have been rendered null and void.

The advancement of nanotechnology in many fields, thus,required development of high performance materials,Nanoscale materials research was pioneered by Gleiter,who coined the term “nanomaterial”. The decresed lengthscale imparts drastically different physical properties to these

materials. For example, it has been demonstrated that ametal, in nanostructured form, behaves like a ceramic.Similar phenomena have been observed with regard to avariety of properties like magnetism, conductivity and evencolor. Perhaps one of the most lucrative areas for thenanotechnologist is catalysis. A variety of chemical reactionstake place on the surface of the catalyst, and the larger thesurface area, the more active the catalyst. Nanoscalecatalysts thus open the way for numerous processinnovations to make many chemical processes more efficientand resource-saving - in other words more competitive. Themedicine segment has also been reaping the benefits ofnanotechnology, with nanobots or nano robots becoming areality. The nanobots can be injected into the blood streamand their motion controlled through external electric field.Thus, they have huge potential for efficient drug deliveryapplications.

Synthesis and CharacterizationThe one major question that needs to be asked if one wantsto delve in nanotechnology is how to manipulate things atsmall scales. Such a task requires advanced techniques fornanostructured materials synthesis, product assemblingcharacterization and control. The synthesis of materials and/or devices with new properties by means of the controlledmanipulation of their microstructure on the atomic level hasbecome an emerging interdisciplinary field based on solidstate physics, chemistry, biology and materials science.

Nano materials and/or devices should have at least one oftheir dimensions in the nanoscale. Thus, there arenanometer-sized particles, nanowires or thin films ofnanoscale thickness. CVD, PVD, inert gas condensation,various aerosol techniques, precipitation from the vapor, fromsupersaturated liquids or solids (both crystalline andamorphous) appear to be the techniques most frequentlyused to generate this type of microstructure. PVD, CVD, ionimplantation and laser beam treatments are the most widelyapplied to produce nanocrystalline surfaces with enhancedcorrosion resistance, hardness, were resistance orprotective coatings. The methods to produce nanomaterialsare usually classified into two groups, the bottom up and thetop down approaches. In the first route, one starts withindividual atoms and builds the nano particles by bringingthese atoms together. PVD/CVD, chemical routes and thoseinvolving amorphous precursors fall into this category. In thesecond route, the bulk materials are brought down tonanoscale by severe plastic deformation. High energy ballmilling equichannel angular extrusion, etc. fall into thiscategory.

Assemblage of nanoscale devices using the nanostructuredmaterials would be the next logical step required to exploitnano science and move into the realm of nanotechnology.Such manufacturing process often draws uponnanopositioning, the technology of moving and measuringobjects with nanometric precision. The machines used forsuch applications combine optical design with advancedmotion control technologies. Piezoelectric devices have the

potential to meet the resolution requirements. However, thenon-linear nature of piezoelectrics means that an externalsensor should be present for position control. Thecapacitance micrometer is ideally suited to this task, beingsmall with intrinsic sub-atomic resolution.

Once the nanomaterials have been developed for a givenapplications and the devices assembled, one has tocharacterize them, and test their capabilities. There in liesthe role of microscopy. With increasing focus onnanotechnology and nanomaterials, the demand for betterelectron microscopes is on. This has been the motivatingfactor for development of the new breed of high resolutionelectron microscopes and the scanning probe microscopes.The impact of such microscopes is huge. For instance,electrochemical processes can be studied at the molecularlevels. Studying the process exhaustively is the first steptowards controlling and tailoring the process.

Achievements of Nano TechnologyThere are three trends in manufacturing: greater flexibility,greater precision, and lower cost. Nanotechnology is aboutadvances in all three. Some of the achievements ofnanotechnology have been enumerated below.

1. Manipulation and bond formation by STM (ScanningTunneling Microscopy). This research hasdemonstrated that direct molecular manipulation andbond formation is feasible, but it’s still hard; we needto reach a state where this is routine and possible withlots of molecules.

2. DNA Sequencing with Nanopores . If one can make avery small and very precise hole, you can solve a wholeclass of problems, of which gene sequencing is onlyone example.

3. Modification of Virus shells . When it comes tonanotechnology, viruses are way ahead of us. Recentresearch piggybacks on this fact by modifying virusshells rather than building complex molecules fromscratch. For example, in one experiement, the CowPeaPosaic Virus was modified to incorporate gold into itsshell, perhaps one day enabling a new methodologyfor mineral extraction.

4. DNA Motors. Ned Seeman has demonstrated that youcan shift DNA from single-to double-stranded byintroducing complementary strands, with the resultbeing the development of “sliding struts”-a three-phasemotor. There is also some older work by Montemagnoat UCLA -interfacing biological motors to siliconsystems.

5. Nanotube inverter . An IBM team led by Phaedon Avouriscreated an inverter, a basic computer device, by drapinga bucky tube over a prepared surface to make a type ofnanoscale transistor.

6. NRAM from Carbon Nanotubes . People are workingon building what they call NRAM out of carbonnanotubesn-“NRAM will be considerably faster anddenser, have substantially lower power consumptionthan flash, be as portable as flash memory, and behighly resistant to environmental forces (heat, cold,magnetism).”

7. IBM’s Millipede . Merkle commented that “Whileelectronics is interesting, it isn’t really quite what we’retalking about. We want manufacturing.” IBM Zurich’sMillipede, which uses an array of STM microscopes,gives the first inkling that we are building a core ofmolecular manufacturing capabilities.

8. Nanolayers . New light emitting materials are madepossible by nanostructuring semiconductor materials.The vertical cavity surface emitting laser (VCSEL) inwhose development Sandia National Laboratory playeda major role is a good example of nanomaterial thatuses layered quantum well structure to produce highlyefficient, low power consumption light sources. A keyto achieve high efficiency and optical control is thequantum confinement that results from designing andbuilding materials with chemically distinct layers thatare on the order of 10 nm thickness.

9. Three dimensional nanomaterials . Molecular self-assembly, hitherto used exclusively in biologicalsystems, is extremely well suited to the production of3-d nanomaterials including porous and solidcomposite structures. Self-assembly methods havealso been used to make nanoscale hybrid organic /inorganic materials. A recent example is the self-assembly of mesoscopically ordered chromaticpolydiacetylene/silica nanocomposites. This materialhas excellent electronic and optical properties whichrenders it useful for LEDs to biomolecular sensors.The origin of these properties lie in the fact that subtleshifts in the organic bond structure causes optical colorchanges.

10. Drug delivery systems . Drug delivery systems havebecome the craze today. For efficient drug delivery, it isimperative to develop reliable magnetic nanoparticles,which can be coated with appropriate medication,injected into the blood stream and then guidedmagnetically to the organ where drug delivery isrequired.

11. Manufacturing . The development ofnanoelectromechanical systems is another huge leapin cutting-edge technologies for the future. Suchdevices are essential for development of nano robotsand assemblers, which move molecule sized particlesinto precise locations, thereby revolutionizing themanufacturing industry.

12. Cooling systems . Advances and nanoscience in formof nanofluids have heavy implications in applicationsrequiring high heat transfer media. With theirtremendous stability and high thermal conductivity,nanofluids truly represent the wave of the future in heattransfer technology.

13. Health sector . Nanotechnology is also making wavesin the health sector as well. Development of nanoscalefilters for steril izing drinking water is an issueparticularly relevant to the third world countries, whichonly have access to dubious sources of drinking water.

The Future ProspectsWith all these wonderful achievements already surfacing fromdifferent directions, it is perhaps pertinent to ask “where is

nanotechnology heading”? The view that nanotechnology willlead to tiny robotic submarines navigating our bloodstreamis ubiquitous. Yet today’s products of nanotechnology aremuch more mundane - stain - resistant trousers, better suncreams and tennis rackets reinforced with carbon nanotubes.There is an almost surreal gap between what the technologyis believed to promise and what it actually delivers.

Back in 1986 Drexler published an influential book calledEngines of Creation: The Coming Era of Nanotechnology, inwhich he imagined sophisticated nano-scale machines thatcould operate with atomic precision. We might call this goal“radical nanotechnology”. Drexler envisaged a particular wayof achieving radical nanotechnology, which involved usinghard materials like diamond to fabricate complex nano-scalestructures by moving reactive molecular fragments intoposition. His approach was essentially mechanical, wherebytiny gears and bearings are integrated to make tiny robotfactories, probes and vehicles. The most compellingargument that radical nanotechnology must be possible isthat cell biology gives us endless examples of sophisticatednano-scale machines. These include molecular motors ofthe kind that make up our muscles, which can convertchemical energy to mechanical energy with astonishinglyhigh efficiencies. There are also ion channels and ion pumpsthat can control the flow of molecules through membranes.Other examples include ribosomes - molecular structuresthat can construct protein molecules with ultimate precisionon DNA.

Drexler argued that if biology works as well as it does,researchers ought to be able to do much better. Biology,after all, uses unpromising soft materials — proteins, lipidsand polysaccharised - and random design methods that arerestricted by the accidents of evolution. Furthermore,molecules are moved around through their continualbombardment by other molecules — what is known asBrownian motion — rather than via pipes and tubes. Weresearchers, however, have the best materials at ourdisposal. Surely we can create what are in effect, syntheticlife forms that can reproduce and adapt to the environmentin the competition for resources.

Even if the most extreme visions of the nanotechnologyevangelists do not come to pass, nanotechnology — in theform of machines structured on the nano-scale that dointeresting and useful things—will certainly play a growingpart in our lives over the next half-century. How revolutionarythe impact of these new technologies will be is difficult tosay. Scientists almost always greatly overestimate how muchcan be done over a 10 year period, but underestimate whatcan be done in 50 years. Sometimes the contrast betweenthe grand visions of nanotechnology — roboticnanosubmarines repairing our bodies — and the reality itdelivers — say an improved al-in-one shampoo andconditioner — has a profoundly bathetic quality. But theexperience we will gain in manipulating matter on the nano-scale in industrial quantities is going to be invaluable.Similarly, there is no point being dismissive about the factthat lots of early applications of nanotechnology will beessentially toys — whether for children or adults - just asdata-storage technology is currently being driven forward bythe needs of digital TV recorders and portable music players.These apparently frivolus applications will provide theincentive and resources to push the technology further.

But which design philosophy of radical nanotechnology willprevail - Drexler’s original “diamondoid” visions orsomething closer to the marvellous contrivances of cellbiology? One way of finding the answer would be to simplydevelop the exising technologies that have driven therelentless miniaturization of microelectronics. This “top-down” approach, which uses techniques likephotolithography and etching, has already been used tomake so-called microelectromechanical systems (MEMS).Such systems are commercially available and havecomponents on length scales of many microns — theacceleration sensors in airbags being a well known example.All we need to do now is shrink these systems even furtherto create true nanoelectromechanical systems or NEMS. Theadvantage of this top-down approach is that a massiveamount of existing technology and understanding is alreadyin place. The investment, both in terms of plant, and researchand development, is currently huge, driven as it is by the vasteconomic power of the electronics and computing industries.But, as we have seen, the disadvantage is that there areboth physical and economic bounds to how small thistechnology can go. Although industry has shownextraordinary ingenuity in overcoming seeminglyinsurmountable barriers already — new ultraviolet lightsources and phase-shifting masks have made feature sizesbelow 100 nm a commercial reality — may be its luck willsoon run out. A more fundamental problem is the importancein the nanoworld of Brownian motion and surface forces.Strong surface forces may make the moving parts of a NEMSdevice stick together and seize up.

So how could we follow biology’s example and work with the“grain” of the nanoworld? The most obvious method is simplyto exploit the existing components that nature gives us. Oneway would be to deliberately remove and isolate from theirnature havitats a number of components, such as molecularmotors, and then incorporate them into artif icialnanostructures. Another approach would be to start with awhole, living organism probably a simple bacterium — andthen genetically engineer a stripped-down version thatcontains only the components that we are interested in.

As we learn more about how bionanotechnology works, itshould be possible to use some of the design methods ofbiology and apply them to synthetic materials. Likebionanotechnology, such “biomimitic nanotechnology” wouldwork with the grain of the special physics of the nanoworld.Of course, the task of copying even life’s simplestmechanisms is formidably hard. Proteins, for example,function so well as enzymes because the particularsequence of amino acids has been selected by evolutionfrom a myriad of possibilities. So when designing syntheticmolecules, we need to take note of how evolution achievedthis. But despite the difficulties, biomimetic nanotechnologywill let us do some useful — if crude-things. For example,ALZA, a subsidiary of Johnson and Johnson, has alreadybeen able to wrap a drug molecule in a nanoscopic container— in this case a spherical shell made from double layers ofphospholipid molecules — and transport it to where it isrequired in the body. The container can then be made toopen and release its bounty.

The entire gamut of biosciences and nanostructured solidscoming together with wonder devices sounds exciting. It doesseem that the future of technology is best viewed at nanoresolutions. The invitation to enter a new dimension ofscience and technology has never looked so alluring before.

Metallic Materials for Marine ApplicationsDr K Srinivasan*

Abstract

Metals have played a key role in the development of humancivilization. Ship building is one of the oldest activities ofhuman kind. Over the years a large number of metals andalloys have been used in the construction of ships and seashore installations. Here an attempt has been made to puttogether the metals and alloys widely used in marineapplications.

Introduction

Components used in ships and harbors are exposed to saltatmosphere since seawater contains about 3.4% salt. It isalso slightly alkaline with pH being 8. It is a good electrolyte.It can cause galvanic corrosion, crevice corrosion and pittingcorrosion. Fig. 1 shows corrosion of ordinary steel in

seawater. Fig. 2 shows resistance of metals and alloys toseawater. Apart from these, salt water can sustain thousandsof types of animal and plant life, including barnacles,mussels, algae and others. These animal and plant formsattach therselves to solid surfaces during their growth cycle.The accumulation of these organisms cause intense andinsidious fouling of structures. Another problem with metallicmaterials especially steel is that it becomes brittle at lowtemperatures below—50C. In cold seawater breakage ofships can occur. This problem also has to be avoided whileusing materials for ship construction. The nature of each ofthe above problem and the metallic materials used to resistthem are discussed in this paper.

Galvanic CorrosionA potential difference usually exists between two dissimilarmetals when they are immersed in a solution such as

Fig 1 : Corrosion of Ordinary Steel in The Sea

seawater or brackish water. If these metals are placed incontact or electrically connected, this potential differenceproduces electron flow between them. Corrosion of the lesscorrosion resistant metal is usually increased and attack onthe more resistant material is decreased as compared withthe behavior of these metals when they are not in contact.The less resistant metal becomes anodic while the moreresistant metal becomes cathodic. Usually the cathodicmetal corrodes very little. This is called Galvanic Corrosion.It is electrochemical in nature. The driving force is the potentialdeveloped between two metals or alloys. Table 1 gives the

potential differences between metals under reversible ornon-corroding condition. In sea water the relative positionsare changed and is given by Table 2(a) and (b). Galvanic

corrosion is more severe in marine atmosphere in seasand near seashore compared to an inland location. Toprevent galvanic corrosion do not put dissimilar metals incontact or give a protective coating (eg. galvanizing iron orsteel) or use sacrificial anode, such as zinc which will corrodein preference to iron which will be intact. Fig. 3 gives thegalvanic compatibility for pump and valve trim in seawater.Valves are manufactured with different materials and withdifferent trims. Trim is the seat of the valve and is made ofmaterials different from the pump and the valve body.Therefore there will be galvanic coupling of the pump andthe valve trim.

Crevice Corrosion

Intense localized corrosion occurs within crevices and othershielded areas on metal surfaces exposed to seawater. It isusually associated with small volumes of stagnant solutioncaused by holes, gasket surfaces, lap joints surface depositsand crevices under the bolt and rivet heads. Therefore it iscalled crevice corrosion or deposit corrosion or gasketcorrosion. Deposits may be sand, dirt, corrosion productsand other solids. These deposits act as a shield and createa stagnant condition under them. Contact between metaland nonmetal surfaces can cause crevice corrosion Wood,plastics, rubber, glass, concrete asbestos, wax and fabricsare some of the nonmetallic materials, which when in contactwith metals may cause crevice corrosion. 18-8 stainlesssteel in contact with rubber gasket when exposed to seawatercan undergo crevice corrosion. The crevice must be wideenough to permit liquid entry, but sufficiently narrow tomaintain a stagnant zone. Normally to be considered ascrevices, they should be less than a few thousands of aninch but should not in any case be wider than (1/8) inch.Crevice corrosion is more intense in solutions containingchloride ions. A long incubation period is necessary.Sometimes six months to a year is required for the crevicecorrosion to start. Once initiated it proceeds at an everincreasing rate. Metals and alloys, which form an oxidepassive film on their surface and become inert and corrosionresistant are more susceptible to crevice corrosion becausethe oxide film is destroyed by chloride ions or hydrogen ionsin solution. To prevent crevice corrosion one should usewelded joints instead of riveted or bolted joints. Avoid lapjoints. Avoid sharp corners and stagnant areas in vesselsso as to facilitate complete drainage. Inspect equipment andremove deposits periodically. Use Teflon gaskets which arenon absorbent. Use welded tubes. Table 3 shows alloysresistant to crevice corrosion.

surface and a liquid is such that repeated loads are appliedto the surface causing very high stresses when thesebubbles form and collapse regularly. These collapsesproduce high stress impacts which gradually removeparticles of the surface eventually forming deep pits,depressions and pock marks. This type of corrosion isminimized by using a more resistant material or by aprotective coating. Stellite, some stainless steels, certaintool steels have good resistance to cavitation damagewhereas cast iron, bronze & steel castings and plates havepoor resistance.

Pitting Corrosion

Pitting is a form of extremely localized attack that results inholes in the metal. These holes may be small or large indiameter, but in most cases they are relatively small. Pitsare sometimes isolated or so close together that they looklike a rough surface. Generally a pit may be described as acavity or hole with the surface diameter about the same asor less than the depth. Pitting is one of the most destructiveand insidious forms of corrosion. It causes equipment to failbecause of perforation with only a small percent weight lossof the entire structure. It is often difficult to detect pits becauseof their small size and because the pits are often coveredwith corrosion products. In addition it is difficult to measure

quantitatively and compare the extent of pitting because of

the varying depths and numbers of pits that may occur under

identical conditions. Pitting is also difficult to predict by

laboratory tests. Sometimes pits require a long time, several

months or years to show up in actual service. Pitting is

particularly vicious because it is a localized and intense formof corrosion and failures often occur with exteme

suddenness. Pitting may be considered as the intermediatestage between general overall corrosion and completecorrosions resistance. A corrosion pit is a unique type ofanodic reaction. It is an autocatalytic process. The corrosionprocesses within a pit produce conditions, which are bothstimulating and necessary for the continuing activity of thepit. Pitting in reality is a special case of crevice corrosion. Allsystems which show pitting are susceptible to crevicecorrosion. For example, stainless steel in seawater. Thereverse is however not true always. Most pitting failures arecaused by seawater and brackish water containing chlorideand its ions. It also occurs in stagnant conditions such asseawater in a tank or seawater trapped in a low part of anyinactive pipe system. Increased velocity often decreasespitting. Stainless steel pump will give good service if it wererun continuously with seawater but would pit if it were shutdown for extended periods. As a class stainless steels aremore susceptible to damage by pitting in seawater. Ordinarysteel condenser tubes are more resistant to pitting thanstainless steel tubes when exposed to seawater or brackishwater. Rapid perforation does not occur in the former. Type316 stainless steel containing 2% Molybdenum are moreresistant to pitting than Type 304 stainless steel, containing18% Cr 8% Ni. The former is suitable for seawater while thelatter is not. To prevent pitting one solution is to use materialthat doesn’t pit. Titanium have very good resistance to pitting.Next comes Hastealloy C, Hasteally F and 316 stainlesssteel in that order. Materials resistant to pitting in quietseawater are given in Fig 5 .

Fig 5 : Pitting in Quiet Seawater

Fouling

Ship bottoms rapidly accumulate barnacles and other

organisms which markedly affect the streamlining andincrease the power requirements. A severely fouled up shipmay require as much as 30% more electric power during its

operation. Similarly the accumulation of macroorganisms inheat exchangers and other such devices severely limits theheat transfer and fluid flow and may result in complete

obstruction. The accumulation of aqueous macroorganismsis a function of environmental conditions. The most severeproblem occurs in relatively shallow water, since in deeper

water there are no surfaces to which the organisms mayadhere. Thus harbour conditions are specially conducive tothe formation of deposits on ship hulls. In general warm

temperatures favour a long breeding season and rapidmultiplication of macroorganisms such as barnacles andmussels. In northern and southern cold seawater fouling

generally occurs in summer months only, where as in tropicalwaters in equatorial regions fouling is practically continnous.Relative motion between an object and water generally tends

to inhibit the attachment of organisms. Thus rapidly movingvessels accumulate only small quantities of organisms andthe major portion of fouling occurs when the vessel is docked.

The same effect is also noted in heat exchangers employingseawater as a coolant. Rapid fluid flow tends to suppressfouling of heat exchangers whereas rapid accumulation

occurs at low fluid rates or during shut down periods. Alsothe nature of the surface strongly influences the attachmentof macroorganisms. Smooth, hard surface offers an excellent

point for adhesion. Whereas rough flaking surfaces tend toinhibit adhesion. For example the fouling of stainless steeland iron occurs initially at about the same rate in seawater.

However after some exposure the surface of iron is coveredby a loosely adhering iron oxide and fouling tends to be lesson iron than stainless steel after long exposure periods.

Fouling by organisms is most effectively inhibited by the useof antifouling paints. These paints contain toxic substancesusually copper compounds. They function by slowly releasing

oppper ions into the aqueous environment, which poisonsthe growth of barnacles and other creatures. A similartechnique is used in closed system where various toxic

agents and algaecides such as chlorine containingcompounds are added to the environment. These methodswork more or less successfully depending on their

application. However, under conditions conductive to thegrowth of aqueous organisms periodic cleaning shouldalmost always be done to ensure unimpeded fluid flow and

to prevent crevice attack Table 5 gives some materialsresistant to fouling. Brackish water is contaminated with

chlorides usually because of tidal action in rivers and bays

near the seas and oceans. Corrosion problems are less

severe in these waters than in full strength seawater but

guidelines for materials of construction are approximately

same.

Ductile Brittle Transition of Steels

Mild steel with 02% carbon has a DBTT of — 50C. As carbon

content increases this temperature increases. Thereforce

carbon content has to be as low as possible. In cold waters,

either when the ship is on the seas or docked in harbours,

mild steel becomes brittle. During World War II some of the

Liberty ships and T2 tankers broke completely into two while

in other instances the brittle fracture did not completely

disable the ship. Moreover mild steel should contain very

low P and N. Both of them raise DBTT. Alloying with Mn and

Ni are beneficial as they lower DBTT. But alloying makes

welding difficult. Welding of mild steel for ship building has

to be done with special electrodes to avoid defects and

strresses. These give rise to brittleness and lower the

toughness due to notch effect. For ship building mild steel

with a low carbon content is to be used.

Conclusion

There are a variety of materials available for marine

applications—Wood, Metals & Alloys, Polymers, Ceramics

and Composite materials. Here a brief overview of metallic

materials used in marine application has been given to

highlight the various options and bring an awareness among

Marine Engineers about materials. In Table 6 , various metals

and alloys used in marine applications are listed.

Failure Analysis of Bolts Used on Dumper Main Pump Assembly—ACase Study

C.Mahendravarman, S.R.Shivakumara & D.B.Prakash*

Abstract

The most common location for fastener failures are in thehead to shank fillet or on threaded fasteners, through thefirst thread roots immediately adjacent to the edge of the nut.The bolt elongates as it is tightened this produces increasedloads on the threads near the bearing face of the nut andadds to normal service stresses.

This failure investigation is on high strength alloy steel boltof M1432 (total length 115 mm and threaded length 40 mm).It report failure of the bolt along the threaded portion due toexcess run out of the thread, use of spring washer and inferiorquality of the material.

IntroductionIn a well-designed mechanically fastened joint, the fastenermay be subjected to either static loading or dynamic fatigueloading.

The primary force in the bolt is tension, which is set up bystretching the bolt during tightening; whereas the mostimportant stress in nut is the shear stress in the threads.Experience suggests that non-axial loading of bolts and studsis one of the most common causes of failure.

Spring washers should not be used under fatigue condition;in fact, any washer is undesirable, as it increases theelasticity of the parts held together by the bolt and so raisesthe range of stress fluctuation to which it is subjected.

Apart form the above another important characteristic, whichhas to be considered, is the metallurgical properties of thebolts. Hence the bolts should be properly heat treated, thesegregation and inclusions rating should be within theacceptable range and free from defects like thread rollinglaps, decarburisation etc.,

The failed bolt microstructure reveals that the sulphideinclusion stringers are segregated along the temperedmartensite bands (white) these tempered martensite bandsare very hard and brittle compared to the adjacent region(the difference in hardness between the bands is @ 60 HV)and this type of microstructure will introduce more stress onthe tempered martensite bands. The stringers of segregatednon-metallic inclusions also act as stress raisers. Hencethis banded type structure and stringers of segregated non-metallic inclusions will produce crack even with small non-axial load.

ConclusionThe failure of the bolt is due to the inferior metallurgical qualityof the material i.e., higher inclusion rating, bands of temperedmartensite (white bands) and regregated inclusions alongthe hard (tempered martensite) bands.

Another important reason for the bolt failure is the excessrun out of the threaded portion from the bearing face. Hencethe end of the bearing face will act as a stress concentrationsite. The bolt elongates as it is tightened, producing increasedloads on the threads near the bearing face of the pump case.This adds up to normal service stresses.

Apart form the above the usage of spring washers also maybe the reason for the failure because it increases the elasticityof the parts held together by the bolt and so raises the rangeof stress fluctuation to which it is subjected.

Steel Slag detection by Thermal ImagingSlag carryover from the furnace to the ladle is securely avoidedby the new SDS slag detection system from Land InstrumentsInternational . SDS records each tap and simultaneouslygenerates a log and graph of the steel/slag data. When a presetprecentage of slag or steel is detected within the definedwindow, an alarm is generated to stop the tap, and the video,text and graph files are saved and identified by tap number forlater analysis.

The SDS camera uses a focal plane array micro-borometer witha temperature measurement range of 600 to 2,0000C and athermal image resolution of 320 x 240 pixels. Its operatingwavelength is 3.9 mm, with a field of view of 6 degrees x 4.5degress and a motorized focusing range from 3 m to infinity.

Treasure hunt on the seafloorGeological Survey of India published a report that more thantwo dozens black smokers have been found undersea indifferent volcano-tectonnic settings. These smokers shows a richmineralization of gold and silver in addition to copper, lead

and zinc. Amongst the hydrothermal chimneys on the sea floor,some are called white smoker because of comparatively coolerwaters and presence of compounds of calcium, barium andsilica, which are white. From one such smoker in SW Pacific,gold inclusions were initially discovered at surprisingly lowtemperature of less than 3000 C.

A hydrothermal vent is a geyser on the seafloor: super-hotmineral rich water is continuously spewed through these ventswhich are deposited at site. Though the sea bottom is anextremely cold place the superheated steam from the womb ofthe earth makes the areas around the vents comfortable forsome rare creatures like eyeless shrimps (at the vents in theAtlantic ocean). These vents are known to exist in the Pacificand the Atlantic occeans at an average depth of about 2100metres in the areas of sea floor spreading along the underwatermountain chain, the Mid Ocean Ridge System that snakesaround the globe.

The hydrothermal vents are formed undersea because someareas along the Mid Oceanic Ridge plates of the earth’s crustare moving apart. This leads to the formation of cracks. Seawater seeps down from these cracks. The molten magmaunderneath the earth’s crust heats up that water and asuperheated steam enriched with minerals finds escape throughthe cracks and fissures. Though the vent water comes out attemperatures as high as 4000 C, it does not boil because of thepressure of the water coloun above.

More than 200 occurrences of hydrothermal mineralization areknown on the sea floor. The best amongst them is in Red Sea. Itis estimated that the vent contains 50 tonnes of gold, 4000tonnes of silver in addition to 94 million tones of ore with 2percent zinc and 0.5 percent copper. It is now believed thathydrothermal vents have been responsible for some of theworld’s richest ore deposits, like the copper ore of Cyprus.Geologists are already thinking in terms of mining some of themineral rich vents of the ocean bed. Problem is the economicviability of such extraction.

Managing high level nuclear wasteSpent fuel

High level nuclear waste consists of spent fuel or highlyradioactive residues left after reprocessing and extractinguranium and plutonium. Most of the radioactivity in spent fuelis due to fission products, which have relatively short half lives.

Their activity will reach background levels in a few thousandyears. Isolation of activity from biosphere for a few thousandyuears is achievable. High level waste is made non-dispersibleby vitrifying (incorporating them into glass, a material which isnon-leachable for thousands of years) it.

The public wrongly believes that vitrification process is storagein glass containers ! India has developed the borosilicatetechnology.

If any waste leaches from glass, it has to penetrate severalprotective barriers such as a stainless steel container, acladding of lead, a casing of titanium (a special corrosion-resistant alloy), several metres of backfill material such as clayor salt or granite before reaching the living environment. Eachof these will last thousands of years.

Titanium in flowing saline water dissolves at a rate of 0.0013mm per year. A six mm layer of titanium used to contain wastemay last at least 4000 years (IAEA, 1981). Roman lead articlessurvived in the Mediterranean for 2000 years with little loss.

Lead casing of 10 cm, which may be used with waste, shouldlast longer.

Archaeologists recovered over 875,000 nails from Inchtuthil inScotland, where Romans hid 12 tonnes of iron nails in AD 86.Nails from the outer few centimetres are heavily corroded; manyof those inside are almost intact after nearly two millennia.

Excerpts from the speech of Shri B.Muthuraman President, IIM & MD, TataSteel in the Press Conference heldduring the 6oth Annual GeneralMeetine of IIM on 11th August2006 in Kolkata

With rapid unprecedented boom inInfrastructuraI projects across thecountry in roads, ports, airports, railwaysand housing sectors; there is bound tobe spectacular rise in the demand forsteel and aluminium. These dynamicforces will in turn exert amazingmultiplier effect on income, output andemployment generation in theIndian economy - Shri Muthuramancommented.

India must aim to enhance its steelproduction to over 100 mt per annumby 2020 as against 300 mt by Chinatoday itself. Similarly her currentaluminium smelting capacity of 1 mt perannum should rise to a 2 mt per annum.Per capita consumption of steel in Indiashould aim to grow from the presentlevel of 30 kg to 330 kg per head in tunewith the pattern of deveIoped countries.

The vision of 10% growth per annum ofthe Indian economy is very much anattainable proposition and not a far cry,if her economic development isspearheaded by the manufacturingsector including ferrous metals.

Given the growing Indian economy andher buoyant metal sector, there isbound to be demand supply gap in theavailability of qualified metallurgists. Atthis crucial junction IIM should step into fill up this impending void. IIM as thelead Institution will have to draw theroad map for enhancing India’sstanding in the global metal industry inthe next 10 years. To meet thechallenges and seize the opportunitiesthe institutional set up of the IIM shouldbe geared up. India will require 20,000to 30,000 metallurgists in the next 10years. IIM should guide and inspiretalented young people to take upmetallurgy as a profession, whichwould be a stable income earner in theyears ahead. The IIM through its

institutional network of 52 Chaptersspread across the length and breadthof the country is poised to usher in reallymeaningful collaboration by andbetween Indian industry, academy andresearchers on a common platform.Series of conferences, seminars andworkshops are going to be organizedfor mutually beneficial interactions.

Arcelor investors reject SeverStaldeal

Arcelor Shareholders rejected amerger deal with Russia’sSeverStal, clearing the way for anagreed $ 32 billion take over byMittal Steel. Shareholdersrepresenting 57.94% of capitalvoted against the plan which wouldhave given SeverStal’s main ownerAlexei Mordashov a key stake in themerged group. At least 50% of thecapital was required to block thedeal. Seeing this vote, the board willnow unwind the agreement with MrMordashov. Originally hailed byArcelor’s board as salvation, thedeal with SeverStal was the primeobstacle to the company’s presentagreement with Mittal Steel to joinforces.

Market for Electronic Waste toExceed $11 Billion by 2009

The global market for electronic wasteis expected to rise at an averageannual rate of 8.8% over the next fiveyears, from $7.2 billion in 2004 to anestimated $ 11 billion in 2009. Thefaster revenue growth will be seen inthe recycled plastics sector, which isexpected to grow at an average of10.2% per year in response toincreased demand for high-valueengineered plastics. Growth in metalsrecovered from end-of-life electronicwaste will continue to outpace thebroader recycled metals market,growing at an annual rate of 8.1%,

Platinum, Palladium use likely to goup

Platinum demand will beat productionin 2006 for an eight consecutive yearsas automakers install more plllutioncontrol devices. The use of platinum inauto-catalysts will exceed 4 millionounces in 2006 compared to 3.8million last year. Platinum demandamong automakers gained 9.5%. Useof palladium also used in auto-catalysts, rose to a four year high lastyear. Automakers are also changingthe mix of metals in auto-catalysts tosubstitute platinum with palladium,whch is cheaper.

The Carbothermic Route toMagnesium

The carbothermic reduction ofmagnesia to produce magnesiumoffers the potential of a lower energyand higher productivity route for metalproduction compared to existingindustrial routes. The reaction ofmagnesia and carbon produces amagnesium and carbon monoxidevapor. Slow cooling of that vapor willallow the reaction to quickly revert andthe prevention of this reversionreaction is a major technicalchallenge. Two main approaches canbe taken to prevent reversion andallow recovery of the metal product;rapid quenching of the vapor anddissolving the magnesium directly in asuitable metal solvent beforereversion can occur. The commercialviability of either carbothermic route tomagnesium is closely connected to bephysical chemistry of each system.

Aluminium

In the 19th centrury aluminium wasconsidered rare and novel. An ingot ofthe ‘new precious metal’ was evendisplayed in 1855 at a Paris exhibition,and at that time the metal was moreexpensive than gold.

Aluminium remained rare until 1886,when two teams workingindependently of each otherdiscovered an electrolytic process forrefining aluminium from bauxite. Thepair simultaneously found that if they

while the market for recycled glasscontinues to be stagnant, with lowvalue attached to recycled glass.

Electronic waste is growing at threetimes the rate of other waste in themunicipal solid waste stream,resulting in the need to rapidly curbtoxins in the waste stream. Electronicwaste equals 1% of solid waste onaverage in developed countries and isexpected to grow to 2% by 2010. Indeveloping countries, electronic wasteas a percentage of solid waste canrange from 0.01% to 1%. However, ledby China, developing countries will bethe fastest growing segment of theelectronic waste market with thepotential to triple output over the nextfive years. (www.tms.org/jom.html)

Insights into siliconsemiconductors

The researchers from the Universityof Wisconsin-Madison examinedthe inimitable 7x7 surface structureof Si (111), the most stable surfaceof silicon. Surfaces and interfacesdominate in today’s silicon devices,since the surface to volume ratiogoes up in small structures. Thesetwo dimensional structures aredifficult to study and the SRC workexplores an aspect that hasremained unexplored onsemiconductors so far. Resultsreveal a very unusual surface bandstructure which can be bestexplained by a mechanism called‘electron-phonon interaction’.Phonons are vibrations of theatoms, which are surrounded byelectrons. By shaking the surfaceatoms the orbiting electrons ‘feel’these vibrations and change theirmovement in a characteristic way.The research work connects twointensively studied fields: electron-phonon interaction that causesconventional superconductivity andsemiconductor surfaces which areof great importance for electronicdevices and semiconductortechnology. The current study is thefirst example of such examinationon a semiconductor surface thoughsimilar research has been done onmetal surfaces. The ultimate goallies in the possibility of tailoringmaterials for a new generation of‘designer superconductors’.

dissolved bauxite in a bath of moltencryolite and passed a powerful electriccurrent through it, molten aluminiumwould be deposited at the bottom ofthe bath. The Hall Héroult Processtakes its name from these co-discoverers - Paul Louis ToussaintHéroult, from France and CharlesMartin hall from the USA. This processenabled the mass-production of themetal, and the first factories went intoproduction two years later.

In industry aluminium is valued for itslight weight, and is used in the aviationindustry where it can cope with thestresses and strains involved withhigh altitude flying. The Wrightbrother’s first aeroplane, whosemaiden voyage was in 1903, had afour-cylinder. 12-horse power auto-engine modified with a 15 kgaluminium makes up 80% of theunladen weight of the 5,300 aircraftflying around the world.

The light weight of aluminiumcontributes to fuel efficiency and overthe life of a vehicle, for every tonne ofaluminium used it will save 20 tonnesof carbon dioxide equivalents whencompared to a tonne of traditionalheavier materials. Aluminium alsoabsorbs kinetic energy, and so for alargely aluminium vehicle in animpact, the structure absorbs much ofthe shock, rather than the vehicleoccupants, and so far this reason it isused extensively in off-road vehiclessuch as the Land Rover.(www.iom3.org)

China & India move up on pollutingnation’s list

“Greenhouse gas emissions fromChina and India are growing veryrapidly at the moment, very muchbecause of inefficient investments inenergy, in power generation.”

According to the World Bank’s LittleGreen Data Book released recentlyChina increased carbon dioxideemissions by 33% between 1992 and2002. India’s emissions rose by 57%during the same period. He said themain reason that the emission fromChina and India are rising so fastcompared to the rest of the world,which is a 15% rise in carbon dioxideemissions between 1992 and 2002,was older & inefficient coal fired powerplants in both countries. While cleanercoal fired plants are possible, Indiaand China cannot afford to make theswitch.

US remains the world’s biggestpoluters accounting for nearly 24% ofall emissions of carbon dioxideglobally, while EU contributing almost10%.

41.79 million tonne Shortfall in Coal tobe Bridged by Imports

SAIL announces its expansion and modernisation programmesSAIL Plans new plant in Bokaro for Rs 20K cr

Steel Authority of India (SAIL) is planning to invest an additional Rs 20,000 crore to put up a five mt greenfield plant in existingBokaro Steel (BSL) site. Under the existing Corporate Plan of the company, SAIL intends to expand its capacity from existing 14.5mt to 22.5 mt by 2011-12 with a total investment of Rs 37,000 crore. The greenfield project is in addition to the company’s existingexpansion strategy. A final decision would only emerge after BSL completes its initial expansion with an investment of Rs 8,000 crore.An early completion of the project would give an advantage to the company for further expanding BSL’s capacity to 8 mt. The 5 mtgreenfield expansion would be undertaken later which would enhance total capacity of BSL to 13 mt by 2020, he said. The 13 mtcapcity will be in line with the global strategy of steel companies, where a minimum size of 10 mt is considered ideal.

It has also decided to invest in new area of businesses which includes setting up a plant for auto body sheets and set up a cementfacility under joint venture. With Bokaro Steel Plant as the spearhead, SAIL plans to set up auto body sheets facility with a capacityof 1.2 mt per annum. The estimated investment for the plant is Rs 1,600 and it will be operational within 28 months. Currently, thecomapny has been producing steel for chassis only.

BSL is also looking at operationalising a 2 mt cement plant under the joint venture route. The company is in talks with Cement majorslike Birla Cement, Jaiprakash group, Shree Cement, ACC, Lafarge, Grasim and Mysore Cement for setting up the new company. Itwill hold 26% equity in the JV which is expected to be finalished in the next three months.

(Economic Times, 17th July 2006).

SAIL plans to put Rs 37k cr into growth

SAIL has announced a revised expansion strategy with an investment of Rs 37,000 crore to face emerging challenges in the light ofinterest shown by global steel giants POSCO and Mittal Steel in the domestic iron and steel space. it includes enhancing productioncapacity to 22.5 mt from the present 14.5 mt within three years from the earlier plan of completing the exercise in five years. SAIL’sexpansion plan envisages an investment of Rs 9000 crore at Bhilai Steel Plant, Rs 6,340 crore at Bokaro Steel Plant, Rs. 4590 croreat Rourkela Steel Plant and Rs 2840 crore at Durgapur Steel Plant. Also an increased investment of Rs 9600 crore has beenenvisaged for IISCO. The proposal includes an investment of Rs 1,553 crore for Salem Steel Plant.

Book Review

“Advanced X-ray Techniques in Research and

Industry” (ed) by A. K. Singh, DMRL, Hyderabad

The book is a collection of papers presented at the

seminar on “Advanced X-ray Techniques in Research

and Industry” organized by Defence Metallurgical

Research Laboratory, Hyderabad during December 4-

5, 2003. It consists of several invited review articles

covering basic crystallography, local texture

measurements with high energy synchrotron radiation,

evolution of textures, texture mapping by scanning X-

ray diffraction, absorption tomography for three

dimensional measurements in bulk materials, ultra

thin films specular X-ray reflectivity, small angle X-ray

scattering, glancing incidence X-ray diffraction and X-

ray line profile analysis. Chapter one briefly covers

crystal geometry and symmetry required for X-ray

diffraction work. Texture mapping by scanning X-ray

diffraction and related methods are nicely covered in

second chapter. It is important to mention here that this

is latest technique for texture mapping and at present

no commercial equipment is available for such

experiment. Texture measurements by high-energy

synchrotron radiation and by normal X-ray diffraction

techniques has been widely covered for a few

materials.

X-ray diffraction and absorption tomography for three-

dimensional measurements in bulk materials have

been described in one chapter. A novel method for non-

destructive characterization of local plastic deformation

is also presented in this work. A brief description of

structural characterization of ultra thin film using

specular X-ray reflectivity technique is presented in one

chapter. Powder and glancing incidence X-ray

diffraction techniques and its application in research

and industry has also been presented. The book covers

the recent progress in instrumentation, evaluation

techniques and some applications of small angle X-ray

scattering. X-ray line profile analysis has also been

discussed in detail covering both experimental and

theoretical aspects and some results have been

presented.

A large number of chapters cover-application of

Rietveld refinement technique for different materials

such as catalytic, oxides, high temperature

intermetallic compounds, superconducting

ferromagnetic compounds and cristobalite formation.

The application of high temperature X-ray diffraction to

different materials has also been discussed. Apart from

this the application of X-ray diffraction techniques to

characterize the materials has been dealt in different

areas such as magnetic materials, nano materials,

aluminum alloys, titanium alloys, biomaterials,

forensic application of textile fabrics, sensors, steels

and surface modifications. It also covers the

geometrical aspects of X-ray diffractometer and related

applications. This includes the historical background

and instrumental considerations of various

equipments. A brief outline of special X-ray based

techniques is also discussed.

Energy in Minerals and Metallurgical Industries-H

S Ray, B P Singh, S Bhattacharjee & V Misra

Metallurgical industries generally consume a large

amount of energy. The energy demand is rising

exponenitally. In Indian context, the energy demand is

almost sure to outstrip the supply. Therefore the

authors’ effort to document in one single text the energy

requirement in both ferrous and non-ferrous metals

industry and the measure available for energy

conservation, Energy recovery and its relation to the

environment is a laudable venture. Theoretical analysis

of the underlying phenomena adds further value to this

treatise energy and environment management

constitute an important subject in most engineering

curricula. The book is expected to meet a long felt need

of both academicians and professional engineers.

Design Handbook for Cold-Formed Steel SectionPart 1 : Section Properties

This publication is a detailed study for a selected range

of cold formed steel sections which are presently being

manufactured in India. INSDAG has taken the initiative

for developing design handbook for cold formed steel

sections in two parts namely, Part I : Calculation of

Section Properties and Part II : Standardization of

analysis and design procedures for various cold

formed steel sections produced in India. In the process

of developing Part I of this Handbook, a series of

calculations have been generated for geometrical

properties (full section properties) of angle, channel,

lipped angle, lipped channel and lipped zed sections.

This includes calculations generating series of charts

for reduced section properties covering specific yield

strength values of 240, 345 and 550 MPa for the

sections mentioned above. (Pub : INS/076;
