Microstructure and Mechanical Properties of 600MPa TRIP Steel Produced by TSCR Process

Yonglin Kang

Abstract

C-Si-Mn TRIP steel was prepared by TSCR process in laboratory.The results of tensile experiment indicated that the ultimate tensile strength was 630MPa,yield strength was 430 MPa,elongation was 29.1%.The results also indicated that the microstructure was composed with ferrite,bainite and retained austenite.The counting of quantitative colour metallography showed that retained austenite volume fraction was about 6.6%.
