Hardening Behaviours Prediction of TRIP Steels with Pre-Strain

Article Preview

The hardening behaviours of transformation induced plasticity (TRIP) steels depended on the martensite transformation from the retained austenite. As a key factor, pre-strain can influence martensite transformation during sheet metal multi-step processes. In order to learn about the material’s properties after pre-deformation, the effect of pre-strain on mechanical behaviours of TRIP steels has been investigated with the strain-induced martensite transformation in pre-strain condition in this study. The analyzed results show that: Hardening rate, strain hardening exponent and necking strain of TRIP steels are related to martensite transformation in deformation
