摘要

Abstract

High strain hardening rate is usually pursued for high ductility. Here we report that moderate strain hardening rate is desired for producing better ductility and high yield strength

which is demonstrated in a medium carbon TRIP steel. By adjusting the temperature for bainitic transformation

the morphology

carbon content and residue stress of retained austenite were tuned to tailor the TRIP kinetics during tensile tests

which produced moderated but long-lasting strain hardening for high ductility while at the same time resulted in high yield strength. This strategy should work well for most materials

which usually have a limited ultimate strength.
