摘要
采用热模拟试验机Gleeble-2000,研究了薄板坯连铸连轧工艺条件下TRIP钢连续冷却转变规律及其组织演变.结果表明:实验钢的相变开始温度较低且随着冷却速度的增大而下降,有利于低温终轧;高温加热抑制相变而变形则促进相变;同时当冷却速度大于10℃时, 开始出现贝氏体转变.
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°C/s.
