摘要(Abstract)：

采用光学显微镜、扫描电镜、X射线衍射仪等研究了0.13C-5Mn冷轧中锰钢经逆相变退火处理后的组织和力学性能，分析讨论了保温时间、加工硬化率以及相变诱导塑性效应(TRIP)对其组织和力学性能的影响。结果表明：0.13C-5Mn冷轧中锰钢经过淬火及逆相变退火后组织主要为超细晶铁素体、马氏体以及奥氏体。随着保温时间的增加，实验钢组织中奥氏体含量先增加后减少，在保温30 min时达到最大值，为24.24%。随着保温时间的增加，0.13C-5Mn冷轧中锰钢的综合力学性能先升高后降低，经930℃淬火20 min并在665℃保温30 min后，实验钢的综合力学性能最佳，其抗拉强度为980 MPa,伸长率为23.7%,强塑积为23.2 GPa·%。
