Abstract

Strain hardening is a most important mechanics for metal and alloy.The TRIP steel has very high hardening ratio dσ/de because of strain induced martensite transforms.The hardening curve is different from other high strength steels metal and the hardening exponent has an analogous parabola shape with strain.The TRIP steel has very high strength and plasticity for its hardening ratio increasing with strain increasing,and the hardening exponent of the TRIP steel has relations with the hardening curve and the martensite transform kinetics.
