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
- New ductile steels with ultra high strength - obtained by a specific alloy and microstructure design
- 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.)
