From the editors

2008 have been an important year for recruitment of

new faculty members. Four new faculty members have

joined the department to strengthen our education and

research in silicon production including feedstock for

solar grade silicon, refining and recycling of metals,

high temperature corrosion and surface science and

finally nano-materials. in addition a professorship

in physical metallurgy was advertised last year and

the top candidate was just recently hired. Finally, a

professor in solar cell materials, expected to be hired

during 2009, will complete our effort to strengthen

our academic staff. the new staff will strengthen our

study programs and research activities in NtNUs

strategic areas materials, nanotechnology and energy

technology. We are much exited to see the influence of

these young and talented new faculty members in the

years to come.

Four of the new faculty members are women, which

bring the fraction of women in academic positions at

the department a significant step in the right direction.

the low fraction of female academic staff members

in natural science and technology is one of the

important challenges in academia. our new talented

female scientists are important role models for all

the excellent female students in our study programs

and we believe that this will motivate a higher fraction

of our female master students to continue with a Phd

study and to further qualify for an academic position in

the future.

the annual number of publications in peer reviewed

international journals continued to increase in 2008.

this is one of the most important strategic objectives

at NtNU and we are contributing strongly to achieve

this objective. the “working horse” in the research is

the Phd students, the post docs and scientists at the

department. We appreciate the long hours they spend

at the laboratories and the hard work they carry out.

the number of Phd awarded in 2008 was 10, which is

lower than expected, which calls for new efforts to

help the Phd students to finalise their theses in time.

2008 has also been a very successful year with

respect to new research projects. our early initiatives

to establish silicon solar cell research in Norway have

paid off in recent years and particularly last year. The

Norwegian Research Centre for Solar Cell Technology

was awarded to the four research institutions

iFe, NtNU, siNteF and Uio in February 2009. our

scientists in this field are key partners in this Centre

with an annual budget of 40 mNoK. several other

projects have also been granted, many of them are

in collaboration with siNteF and industrial partners.

Finally, basic science has also been strengthened,

particularly by the grant for a strategic University

Program (sUP), and two projects supported by the

FriNAt and FriteK programs. We acknowledge

the financial support from the research Council of

Norway and our industrial partners.

the strong growth in solar cell research has also

paved the way for addressing the need for a new

research infrastructure and state of the art labora-

tories. our vision of a new building “solbygg” are

becoming closer to realization day by day. the financial

crises has given new challenges with respect to indu-

strial support for the infrastructure, while on the

other hand we hope that this turns in favour of funding

from the government. We believe that during the next

coming months the funding for our new infrastructure

will be in place.

hydro Aluminium has been one of our key industrial

partners in the past and is certainly an important

partner also in the future. Both hydro Aluminium and

NtNU were concerned with the declining research and

education activity related to aluminium in recent years.

hydro Aluminium is strongly supporting our effort

to strengthen our aluminium activities and has given

financial support to hire two new faculty members,

one in physical metallurgy as described above and one

in aluminium electrolysis technology. Unfortunately,

we have not been able to identify candidates for the

second position. however, instead we will strengthen

the research on primary aluminium production by

hiring an adjunct professor and recruiting a young

and talented scientist, with the intention to qualify

for an academic position. We are very pleased with

the support from hydro Aluminium and their efforts

to strengthen the unique research triangle between

hydro, siNteF and NtNU. the research Council of

4

will continue their studies with a Phd degree which

will balance the fraction of foreign and domestic Phd

students at the department.

the annual report has the same outline as we have

used the last six years. the first part comprises short

reports giving an impression of the current research

conducted in the four research groups, the annual list

of publications and conference proceedings and the

laboratory infrastructure. the first part is intended to

give external readers an impression of the research

being performed. the second part, which comprises

an overview of the staff, master students and Phd

students, last years masters and Phd candidates and

their thesis’ titles and finally extracurricular activities,

is presenting a comprehensive overview of the annual

activity and is more intended for the archives.

We will like to acknowledge the scientific staff for

their contribution to this report. Particularly we would

like to acknowledge secretary Åse Lill salomonsen

and the other members of the administrative staff for

their effort.

From the editors

Norway has during 2009 carried out an evaluation of

research in chemistry in Norway. the electrochemistry

and inorganic chemistry groups have been evaluated

and both research groups received relatively good

scores and were recognized for their healthy research

culture. several recommendations for improvements

are suggested by the expert panel, particularly with

respect to strengthen basic science and, improve the

publication rate, particularly in high impact journals.

the implementation of the recommendations will be

initiated in near future.

excellent student recruitment to our student

programs has continued in 2008. our study program

in materials technology was recognized among the

students at NtNU to be the best master program in

technology. We believe this does not come by itself,

but reflects our continued effort to improve the quality

of our study programs, to include students in our

research activities and “the open door” policy. this is

an important recognition that we are on the right track.

this year we have also reasons to expect that a larger

fraction of the master students graduating in 2009

Thermodynamics is an integral part of high

temperature materials technology. For the evaluation

of process routes in synthesis of new materials,

computational thermodynamics is an essential tool,

and the importance of thermodynamic modelling in

the improvement of industrial production processes

and of materials degradation, can not be under-

estimated. As the application of thermodynamics

becomes indispensable in industries dealing with

production of bulk materials and/or energy

conversion, personnel competence in this area –

both in the scientific community and industry -

will be a cornerstone.

As such, the cross-sectorial “KmB” project

(competence project with user support) thermotech

was commenced at siNteF/NtNU in 2003, with a

projected duration of 6 years, aimed at jointly building

new- and supporting/building bridges between

established thermodynamic competence in the

different groups at siNteF materials and Chemistry

and the Faculty of science and technology at NtNU.

the overall scientific and technological goal held for

the thermotech project was to deliver new, advanced

thermodynamic modelling tools to Norwegian

industry as well as develop experimental methods

for high temperature materials technology, educate

Phd candidates and develop a strong joint research

community at siNteF and NtNU, which can serve the

industry in the field of computational thermodynamics

applied to high temperature materials technology.

the project, which had a total budget of 48.3 mNoK,

was funded by NFr, the Norwegian primary aluminium

producers, the Norwegian ferroalloy producers and

statoilhydro, and was one of the first broad KmB

consortiums at siNteF and NtNU in this field with

shared support from different industries.

the main areas in which the thermotech project has

made major scientific and technological contributions are:

•Developmentofinternationallyrenowned

ferroalloys- and solar grade silicon databases.

• Establishmentofafundamentalunderstandingof

the chemical and mechanical stability of materials in

the Al-electrolysis cell.

• Establishmentofanewmethodologyforcouplingof

thermodynamics and fluid flow in the modelling of

metallurgical processes.

•Newdataandafundamentalunderstandingof

the metal dusting – high temperature corrosion

phenomenon in the production of syngas.

For the ferroalloys industry, the database development

was mainly focused on improving the manganese and

chromium mn/Cr-Fe-si-C quaternary alloy systems,

as well as the Cr2o3/mno-sio2-Cao-Al2o3-mgo-Feo

oxide thermodynamic data in existing, commercial

databases.

With the rapidly expanding Norwegian solar cell

industry – with roots in the si metal producing

industries- the team set out to establish the

world’s best thermodynamic and kinetic database

for solar Grade silicon (soG-si) and its important

trace elements (such as P, B, Fe, ti, Al, Ca, o, C,

N). An example of boron distribution data obtained

in the project is shown to the left. the project can

successfully claim that siNteF/NtNU now holds the

world’s most complete thermodynamic database

for soG-si and its most important impurities. this

database is already in use in essentially all si

production and refining projects currently running at

siNteF/NtNU.

For the Aluminium industry, a significant contribution

by the thermotech project is the understanding

of the role of sodium (Na) in the deterioration of

electrolysis cell bottom linings. it has been shown

that Na diffuses through cathode carbon and changes

its wetting properties so that the cryolite bath can

enter the pores in cathode carbon, and react with

underlying refractory brick. if it wasn’t for sodium,

the refractories would last forever! Based on this

knowledge, the aluminium industry can now work on

solutions for reducing the Na attacks on the linings and

thus increasing the lining lifetime. this is an important

step towards cutting refractory costs and reducing

landfill of waste materials.

the “holy grail” of modelling multi-phase

metallurgical processes and reactions is to establish a

eXtrACtiVe metALLUrGY

highlights from the “thermotech” project

6

eXtrACtiVe metALLUrGY

joint treatment of thermodynamics and fluid dynamics.

to solve this computer-intensive task, the project team

used a silicon refining reactor as modelling case and

took a “module- based” approach in order to enable

the model development. modules to describe the

thermodynamics and physical properties (viscosity,

surface tension etc) of reacting species and reaction

products (gases, slags, metal phases) were developed.

these “modules” were called upon in a CFd framework

which made a simplified model description of the

multiphase flow in the refining reactor. the established

model has been used to successfully reproduce

refining data measured during industrial refining

campaigns carried out at the elkem thamshavn plant

and at the Fesil holla plant. the project has brought

the vision of developing a fully fledged tool to describe

reactive multi-phase flow significantly closer to

realisation!

reforming of natural gas to syngas (Co & h2) is the

most critical process step in gas-to-liquid conversion

processes, e.g. methanol or synfuel production.

in order to render natural gas reforming more

ecological and economical, the current and upcoming

processes seek to reduce the steam content in the

process gas while increasing the overall reforming

capacity. however, metal dusting corrosion (mdC) of

the structural material imposes a limit on optimal,

reliable, and safe syngas production under these

conditions. the work carried out in thermotech has

contributed to being able to understand and predict the

corrosion rate of materials used in high temperature,

carbon-saturated gaseous environments during

production of syngas. this knowledge is applied to

selecting new, more corrosion resistant alloys in new

and existing syngas installations. Longer material

lifetime will promote both increased safety and cost

reductions in the future.

Perovskite oxides are an important group of

ceramic materials with the common formula ABO3.

Several perovskites such as PbTiO3 and KNbO3 are

ferroelectric, meaning that they exhibit a spontaneous

electric polarization that can be switched by an

external electric field. Other perovskites are

multiferroic, meaning that they exhibit both

ferroelectric and ferromagnetic properties. BiFeO3 is

a multiferroic material which has gained huge interest

in the recent years because of its ferroelectric and

antiferromagnetic behaviour.

With the current trend in miniaturizing electronic

components, sensors and other technological devices,

nanostructuring of materials become increasingly

more important. Nanostructures of ferroelectric

materials are used in a variety of applications

such as non-volatile ferroelectric random access

memory, nanoelectromechanical systems, nanoscale

capacitors, advanced sensors, energy-harvesting

devices, photonic crystals and in photocatalysis. For

the wide-spread use of these applications in the future

it is desirable to fabricate the nanostructures by

cost-effective and large-area methods, which favours

chemical bottom-up methods in contrast to physical

top-down methods such as lithography. so although

controlling the growth of such nanostructures is a

challenging task it has a high impact for future use.

the inorganic materials and Ceramics research

group, headed by Professor mari-Ann einarsrud

and Professor tor Grande, has studied the growth

iNorGANiC ChemistrY

and properties of nanostructures of ferroelectric

perovskites since 2003. our main efforts have been

in synthesizing one-dimensional nanostructures of

Pbtio3 and KNbo3, and in studying finite size effects

in BiFeo3. the Phd students Per martin rørvik and

sverre magnus selbach, and post doc Guozhong Wang

have been the main contributors to this work.

For a controlled growth of Pbtio3 nanorods, we

have developed a hydrothermal synthesis method to

grow nanorods on srtio3 substrates. hydrothermal

synthesis is a relatively simple method to obtain

crystalline material at much lower temperatures

compared to other synthesis methods. in our synthesis

procedure an amorphous Pbtio3 precursor was

mixed with a surfactant and heat treated at 180 °C

in the presence of a single-crystal srtio3 substrate.

hierarchical nanostructures of Pbtio3 nanorods were

obtained by controlling the synthesis parameters (Fig.

1). the anisometric growth of the nanorods is proposed

to occur by self-assembly of cube-shaped or facetted

nanocrystals.

the domain configuration of these Pbtio3 nanorods

has been studied by transmission electron microscopy

(tem) and piezoresponse force microscopy (PFm) in

collaboration with the tem group at the department

of Physics (Professor randi holmestad) and the oxide

electronics group at the department of electronics

and telecommunications (Professor thomas tybell).

the as-synthesized nanorods were shown to have the

polarization direction in the longitudinal direction.

alumina membranes as templates in which a Pb-

ti sol was infiltrated. After subsequent drying and

annealing, and removal of the template by immersion

in Naoh, Pbtio3 nanotubes were obtained (Fig. 3). the

template-assisted method is an easy method to obtain

nanotubes of perovskite oxides, but necessitates high-

temperature treatment to crystallize the material and

typically produces polycrystalline tubes.

our group has also developed a hydrothermal

method for synthesizing orthorhombic single-

crystalline KNbo3 nanorods, by reacting Nb2o5 in

a Koh solution, using a surfactant as structure-

directing agent. high-quality KNbo3 nanorods were

only obtained in a narrow window of synthesis

parameters. the phase transition temperatures for

the orthorhombic to tetragonal and tetragonal to cubic

transitions of the nanorods were significantly lower

than that of the bulk KNbo3 materials, reflecting a

finite size or disorder effect.

A detailed study on the strong size-dependent

properties of the multiferroic compound BiFeo3 has

been conducted using X-ray diffraction and differential

scanning calorimetry. Nanoparticles with mean

diameters of 11 - 86 nm were made by calcining a

polymeric BiFeo3 precursor at various temperatures.

When the nanoparticle size decreased the polar

distortion of the unit cell decreased, the polar

displacements of Bi3+ and Fe3+ relative to the oxygen

sublattice increased, and the Néel temperature (the

onset of antiferromagnetic ordering) decreased (Fig.

4). the combination of increasing polar displacements

of cations and decreasing unit cell distortions sheds

light on the microscopic origin of finite size effects

in ferroelectric nanoparticles. Ferroelectricity

disappears at small dimensions due to loss of

cooperative ordering of cation displacements, but

polar displacements on a local scale prevail. the origin

of finite size effects is decoupling of ferroelectric

moments, hence ferroelectricity is lost through

disordering rather than a displacive process. the

decrease in the Néel temperature can be rationalized

from decreasing Fe-o-Fe angle due to increasing

displacements of Fe, and increasing Fe-o bond

lengths. Both microscopic structural changes leads

to decreasing overlap of Fe 3d eg and o 2p orbitals,

and antiferromagnetic ordering vanishes at lower

temperatures. Combined with recent observations

of increased magnetization of nanoparticles, these

are promising results with respect to the possibility

of making small multiferroic nanostructures for

technological applications.

these basic research studies have shown the ability

of relatively simple chemical methods to synthesize

nanoparticles and hierarchical nanostructures of

a technologically very important group of ceramic

materials. in our work we have also shown that the

properties of the nanostructured materials differ

from their bulk counterparts, which is important in

applications. A list of publications can be found at the

group’s homepage:

Microstructure control during thermo-mechanical

processing of metals and alloys is essential to

optimize processes and taylor-make material

properties to specific applications. Key processes

are recrystallisation and grain growth, where the

evolution in microstructure and texture results from a

complex interplay between a number of material and

process parameters. In this context it is important

to have adequate simulation tools to replace time

consuming and costly experimental parametric

studies and for analyses and numerical experiments,

to explore parameter relationships which are not

easily available experimentally.

monte Carlo (mC) simulations are a powerful

and versatile computer simulation approach used

in relation to a variety of materials problems. the

mC method uses random numbers to approximate

solutions, and it is often used to solve complex

or nonlinear problems. in a recently finished Phd

work (egil Fjeldberg) 3d mC simulations were

used to investigate a number of problems related

to microstructure and texture evolution during

recrystallization and grain growth in polycrystalline

materials. in the context of grain growth and

recrystallisation, the method used is the so-called

Potts monte Carlo model, in which a microstructure

is mapped onto a 3d discrete lattice by assigning

each volume element in the lattice a crystallographic

orientation oi (i = 1:Q) so that all lattice sites within a

“grain” have the same orientation. inert particles are

incorporated by assigning clusters of sites a unique,

non-changeable index without any crystallographic

orientation. the grain boundaries are represented

only implicitly as surfaces separating neighbouring

elements of unlike orientation. the grain boundaries

may have different energies and mobilities depending

on the misorientation between the grains. due to the

computer power requirements parts of the work has

been done at the supercomputer facilities provided by

the Norwegian metacenter for computational science,

NotUr.

Fjeldberg’s Phd work is here exemplified through

the simulations on abnormal grain growth in the

presence of particles. Grain growth may be divided

into two types, normal grain growth and abnormal

grain growth (or secondary recrystallisation). during

normal grain growth, the microstructure coarsens

uniformly, and there is generally a relatively narrow

range of grain sizes and shapes, and the form of the

grain size distribution is usually independent of time.

Abnormal grain growth, on the other hand, refers to

the process where a few grains in the microstructure

grow at the expense of a fine grained matrix. Usually

also a bimodal grain size distribution develops,

consisting of a few large, abnormally grown grains

and a large amount of small, retained matrix grains.

Abnormal grain growth is observed in a wide variety of

polycrystalline metals and ceramics, and it may or may

not be desirable. For example, the abnormal growth of

{110} < 001 > Goss-oriented grains in transformer steel

improves magnetic permeability and loss properties.

in contrast, abnormal grain growth in copper films

used in electronic interconnects causes a bimodal

grain size distribution that is detrimental to reliability.

the avoidance of abnormal grain growth at high

temperature is generally also an important aspect of

grain size control in steels and nonferrous alloys, e.g.

aluminium.

it is generally accepted that abnormal grain growth

cannot occur in an “ideal grain assembly”, i.e. a

simple single-phase uniform grain structure with

constant and isotropic properties). most assumptions

concerning the origin of abnormal grain growth

assume some kind of advantage, as a condition for

the occurrence of abnormal growth. this advantage

is most commonly related to size, but can also be

related to texture where certain special boundaries

experience a higher mobility, or, in the case of thin

films, to surface effects. it is also well known that

second-phase particles can be used to control grain

size during normal grain growth. the use of particles

to refine grain size is important in e.g. steel making

and in the welding of certain metal alloys, including

aluminium. however, it is also common knowledge

that abnormal grain growth can develop in a matrix

pinned by particles when the pinning force somehow

is lowered. in spite of a lot of work and many efforts,

the general conditions and behaviour of abnormal

grain growth is poorly understood. in a recent work by

3d Potts monte Carlo simulations of abnormal grain growth

PhYsiCAL metALLUrGY

11

holm and co-workers at sandia National Laboratories

used a 2d Potts monte Carlo model to test whether

abnormal subgrain growth (mobility driven) could be a

possible nucleation mechanism for recrystallisation.

the present work was an extension of this previous

work to 3d and with a particular focus on the influence

of particles on mobility-driven abnormal grain growth.

the question asked, was whether mobility-driven

abnormal grain growth can be reduced or inhibited by

adding second-phase particles to the microstructure.

if this is possible, materials which are subjected to

conditions for mobility-driven grain growth and which

thus may be weakened due to abnormal grain growth,

can get considerably improved by addition of second

phase particles.

however, unfortunately the simulations did not

confirm our hypothesis. the simulation results

are exemplified by the temporal evolution of the

3d microstructure in the case of 10 vol% particles,

Figure 1. it is clearly seen that in contrast to what

one get during normal curvature driven grain growth

with particles, Zener pinning is not obtained, i.e. the

particles in this case are unable to stabilize the grain

structure. instead the particles seem merly to have

a small inhibiting effect on the number of abnormal

grains, and simulations for various volume fractions

of particles, have shown that this effect has only

noticeable influence for volume fractions above 5

vol%.

however, in spite of the “negative” result this

example clearly illustrates the use of computer

simulations as a powerful tool to do numerical

experiments and test hypotheses that are not

easily, and sometimes not even possible, to do

experimentally.

New type of precipitate with belt-like morphology is

observed in Hf-containing aluminium cast alloys.

Nanobelt-like precipitates are observed in hf-

containing aluminium cast alloys after heat treatments

(Fig. 1). these nanobelt-like precipitates exhibit

straight, bent or twisted morphologies and they are

randomly distributed throughout the specimen. each

nanobelt has a uniform width along its entire length.

the nanobelt precipitates are typically 60-240 nm

wide, 10-40 nm thick and a few to several tens of

micrometers long. Quantitative compositional analysis

and hrtem investigations from one precipitate

reveal that the nanobelt precipitate has a si2hf-type

structure, which is orthorhombic.

A high density of belt-like precipitates is revealed

from microstructural observation by sem (Fig. 2). the

present nanobelt precipitate is noncoherent with the

aluminium matrix, and it is not yet clear what effect the

precipitates have on the mechanical properties.

The background of this project is the potential for

development of pure and ultra-fine grained titanium

for biomedical applications. The project is financed by

the Norwegian Research Council under the NANOMAT

program and is organized at SINTEF in Trondheim.

in recent years, commercial pure (CP) ti processed

by methods of severe plastic deformation (sPd) has

attracted growing interest among materials scientists.

this interest is based not only on the potential for

important applications such as medical implants with

better biocompatibility and no toxic alloying elements,

but also due to the potential to match and improve the

mechanical properties above that of the conventional

alloy ti-6Al-4V.

high resolution eBsd has been extensively employed

to quantitatively characterize the microstructure

evolution during sPd. it is widely known that the Kikuchi

diffraction patterns become poorer with increasing

accumulated strains and hereby residual stresses

introduced by sPd. therefore, there is no literature

characterizing the highly-strained microstructures by

means of eBsd, e.g. equal channel angular pressing

(eCAP) followed by high pressure torsion (hPt).

A removal of the residual stresses in the deformed

samples seems to be a promising approach and an

example of the corresponding structure (eBsd), is

shown in Fig.1a. the material processed by eCAP and

subsequently deformed by hPt keeps dimensions

~10mm in diameter and 0.7mm in thickness (Fig. 1b).

here, the eBsd technique reveals the cross section

structure after hPt at a position 3mm from edge. Fig.1a

shows that a bimodal - and equiaxed ultrafine grained

microstructure is obtained. the corresponding size

distribution in Fig.1c shows that there are two peaks in

grain size, i.e. around 100 nm and 700 nm respectively.
