Activités de recherche :

Principalement, mes activités de recherche
concernent la métallurgie physique des aciers à haute résistance et je consacre
la majorité de mon temps de recherche d'une part à la caractérisation
microstructurale multi-échelles des aciers martensitiques revenus et d'autre
part à l'établissement de liens entre la structure et les propriétés mécaniques
usuelles (résistance à la traction, ténacité, résistance à la fatigue).
L'objectif majeur des travaux débutés depuis 15 ans est de définir de nouvelles
nuances à propriétés améliorées pour des applications aéronautiques et outillage
de
mise en forme.
