Breakthrough & modelling programs

Objectives

  • Preparation of future product developments for automotive applications
  • Development, capitalisation, diffusion and use of metallurgical knowledge through models

 

Breakthrough

 

This research program is responding to the continuous technological challenges from car makers. Here are some examples:

 

Weight reduction


  • Low density very high strength steels: a direct answer to weight reduction, without the necessity of thickness reduction - example: steel alloying with light elements (Al or Si)

Low cost and improved In-Use Properties


  • Ultra fine-grain steels:  produced with new thermomechanical treatments or adapted chemical compositions
Safety
  • New ductile steels with ultra high strength - obtained by a specific alloy and microstructure design
Improvement of rigidity
  • Steel-based composites - to improve the young modulus and the density of steel at the same time, as both properties are key in structure dimensioning

 

Modelling

  • Developing and capitalising on metallurgical knowledge
  • Putting this knowledge at the disposal of the plants and R&D teams through models integrated in a user-friendly software

 

Main breakthrough & modelling competences

  • Experimental simulation of thermomechanical processes (hot rolling and annealing, welding etc.)
  • Fine characterisation of the microstructure (Electron microscopy, X-ray diffraction, metallography)
  • Theoretical bases in metallurgy applied to product development and modelling (phase transformation, precipitation, mechanical properties, damage resistance etc.)
