Abstract

Abstract

By using a thermomechanical simulator, the laws of continuous cooling transformation and microstructure evolution of TRIP steel produced by TSCR were investigated. It is found that the phase transition temperature during continuous cooling is lower and decreases with the increase of cooling rate, which is beneficial to lower the finishing temperature. A higher heating-up temperature suppresses phase transformation, on the contrary, deformation can promote it. Bainite was found when the cooling rate surpassed 10℃/s.
