Abstract:There is a general inverse relationship between strength and toughness in low‐carbon steels. The transformation‐induced plasticity (TRIP) effect of retained austenite (RA) can help overcome this contradiction by providing strain hardening and transformation toughening during service. In this study, the effect of RA on the microstructure evolution, cryogenic mechanical properties, and fracture behavior of multi‐alloyed Ni‐containing steel is explored. Two well‐established techniques are employed to tailor the R… Show more
