摘要(Abstract)：

用光学显微镜和X射线衍射仪研究了高强度冷轧相变诱发塑性(TRIP)钢经过热处理后的显微组织和织构,提出了用面探测器同时测量fcc相与bcc相极图的方法,并对bcc相热处理前后织构变化进行了分析。实验结果表明,冷轧TRIP钢热处理后的显微组织为铁素体、贝氏体及残余奥氏体的多相组织,冷轧TRIP钢的主要取向为{112}〈110〉,以及{001}〈110〉和{332}〈113〉,而热处理后{112}〈110〉密度降低,同时{001}〈110〉消失。分析了热处理工艺对冷轧TRIP钢显微组织的影响并计算了残余奥氏体体积分数,讨论了TRIP钢中显微组织形貌、残余奥氏体体积分数以及残余奥氏体中碳含量对其力学性能的影响。
