Evolution de la microstructure des alliages d'aluminium 6XXX durant la mise en forme

Résumé des résultats (Abstract) (Anglais)

Al-Mg-Si-(Cu) aluminum alloys developed for automotive application have complex chemistries and complicated precipitation paths. Their microstructure evolves continuously during processing, leading to potentially inhomogeneous precipitate distributions that influence the formability of these alloys. The goal of this proposal is to better understand the different precipitation sequences that exist in specific alloys of this family during thermomechanical processing, aiming to improve their mechanical response and the efficiency of the production line. As this project develops, it may evolve to include a study of instability and failure during bending of sheet from such alloys.
