摘　　要：通过Q-P-T钢微观组织EBSD图建立二维有限元模型,利用计算机对由TRIP效应产生的应力松弛对Q-P-T钢微观组织和马氏体相变的影响进行模拟研究。结果表明,应变较小时,马氏体相变基本不发生,随着应变的不断提高,应力松弛效应能显著延缓和抑制Q-P-T钢中残余奥氏体向马氏体的转变。The two dimension finite element model of Q-P-T steel was built by the EBSD diagram. The effect of stress relaxation by TRIP on microstructure and martensite phase transformation of Q-P-T steel were simulated and studied by computer simulation. The results show that martensitic phase transformation do not occurs when the strain is small. And the stress relaxation effect suppress and delay the process from austenite phase to martensitic phase in Q-P-T steel with the strain increases constantly.
