Improved work hardening of a medium carbon-TRIP steel by partial decomposition of retained austenite

In this study, the microstructure and mechanical properties of the 0.56 wt % C transformation-induced plasticity (TRIP) steel are investigated by conducting tensile tests at a wide span of deformation temperatures (25–400 °C) and strain rates (0.001–1 s−1). The target is to explore the stability of retained austenite (RA) at various temperatures and strain rates, and the influence of the RA stability on the TRIP effect. Tensile strength...
