Abstract

Two kinds of TRIP(TRansformation Induced Plasticity)steels were heat treated at different bainite temperature in GLEEBLE3500.Mechanical properties and retained austenite stabilization of TRIP steel were invested by static tensile test and XRD(X-Ray Diffraction).The results show that high retained austenite and carbon content in retained austenite can lead fine comprehensive performance.Other side,a model was established which describe the relation between retained austenite and true strain.The model can predict experimental results well.
