| Abstract: | C-Si-Mn TRIP steel was prepared by TSCR process in laboratory simulation. The results of tensile experiment indicated that the mechanical properties were the tensile strength of 610 MPa, the yield strength of 430 MPa, the elongation of 28.4%, and the ratio of yield strength to tensile strength of 0.70. The micmstructure was comprised of ferrite, bainite and retained austenite. The result of quantitative colour metallography showed the retained austenite fraction around 5.8%. |
