INTRODUCTION

This poster summarizes some relevant research developed for the automotive sector at CEIT’s Materials and Manufacturing Division. The development of new materials, processing routes and inspection techniques are key for facing the industrial challenges: •  Weight reduction with the subsequent energy saving •  Reliability of the components

MICROSTRUCTURE DESIGN FOR AUTOMOTIVE COMPONENTS. NON-DESTRUCTIVE TECHNIQUES Development of Advanced High Strength Steels (AHSS) based on boron metallurgy and application of these new grades into hot stamping lines: •  Economical route to increase the safety of vehicles reducing weight. •  Understanding the process parameters/final microstructure

relationship. •  Obtaining tailored microstructures for specific areas in the

component.

POWDER METALLURGY FOR AUTOMOTIVE •  Highly efficient material and energy “near net shape” technology •  Economical production of large number of parts with high

reproducibility and close dimensional tolerances. •  Highly complex geometries with excellent precision, •  New alloy systems and/or thermochemical low pressure carburizing

(LPC) process for obtaining high performance products. INNOVATIVE HEAT TREATMENT TECHNOLOGIES Substitution of induction heating by laser in surface hardening of components such as crankshafts. •  Successful implementation implies understanding microstructural

changes provoked by the change of technology.

VISION AND MONITORING •  Development of intelligent and automatic systems for industrial

handling and monitoring. •  Implementation of multi-view metrology systems for inspection

of complex containers for automotive parts. •  Development of an assistant software tool in maintenance tasks

based on augmented reality: •  Training of operators to assure quality, reliability and safety in the

production environment. •  Guiding users in assembly/disassembly tasks

CONCLUSIONS

•  The results gathered in this poster illustrate the importance of a multidisciplinary approach in research for the automotive industry

•  Focusing research activities for the automobile industry on Metallurgical Processes and Components CEIT expertise extends from Modelling to microstructural and mechanical characterization, as well as NDT inspection and Vision.
