Presentation

Mes travaux de recherche s’intéressent au lien indissociable entre transformations de phases, microstructures et propriétés mécanique des aciers à très haute résistance, aciers utilisés principalement pour l’allègement des structures automobiles et donc la réduction de l’empreinte environnementale du transport. Mes contributions scientifiques majeures concernent les mécanismes de plasticité comme le maclage mécanique et les transformations martensitiques, la nature de leur écrouissages induits (aciers TWIP, TRIP), les effets de taille et de distribution en plasticité (aciers DP, martensitiques trempés et revenus). Ses travaux actuels portent aussi sur les mécanismes de transformations de phase dans les aciers duplex de 3ème génération (Bainitiques Sans Carbure, Medium Mn et Q&P) et les mécanismes d’austénitisation au sens large (interactions recristallisation/transformation, enrichissement/dissolution des carbures, conditions d’interfaces LEP/LENP, réversion de l’austénite). Mes travaux ont toujours cherché à allier expériences (MET, MEB, essais mécaniques) et modélisations (champs moyens ou locaux, en micromécanique ou en transformations de phases). Un tournant dans mon activité de recherche a été l’utilisation de plus en plus systématique des grands instruments (synchrotron) à partir de mon arrivée à l’IJL. Vous trouverez la liste de mes travaux à jour sur https://orcid.org/0000-0001-6658-9231. L'actualisation de la base HAL est en cours.
