Abstract

L'acier à haute résistance et aptitude à la mise en forme selon l'invention est élaboré à l'aide de compositions et de procédés permettant la formation d'une microstructure austénitique et martensitique dans l'acier. Le carbone, le manganèse, le molybdène, le nickel, le cuivre et le chrome peuvent favoriser la formation d'austénite stable (ou méta-stable) à température ambiante par des mécanismes tels que l'abaissement des températures de transformation pour les constituants non martensitiques et/ou l'accroissement de la trempabilité de l'acier. Des cycles thermiques utilisant un refroidissement rapide au-dessous de la température de départ de la martensite, suivi d'un réchauffage peuvent favoriser la formation d'une austénite stable à température ambiante en autorisant la diffusion du carbone dans l'austénite à partir de la martensite.
