Abstract

The synergy of high strength and good ductility remains a critical challenge in the development of advanced precipitation-hardened stainless steels. To clarify the relationships between strength and plasticity-toughness in semi-austenitic precipitation-hardened stainless steels, we systematically examined the microstructure evolution behaviors of core–shell austenite structure in PH17-7 stainless steel under RH conditioning and aging treatment, and explored the mechanism how these evolution behaviors governed the deformation behaviors of the steel. Under the aging conditions, fine Cr 23 C 6 carbides (
