| Abstract Scope |
Ductile fracture toughness in high strength steels is limited by nucleation, growth, and coalescense of voids. Shear localization of void sheets originating from submicron grain-refining carbides limits local ductility and macroscopic toughness. In recent years, attention has focused on developing steels exhibiting transformation-induced plasticity (TRIP) in order to increase fracture toughness while maintaining high strength levels. Here finite element models of particle-containing representative volume elements (RVEs) are used to investigate the effects of key material properties, including austenite stability and interface adhesion, on the local voiding processes. The studies probe the mechanisms by which TRIP steels achieve high toughness and identify directions to further optimize toughness. |
