摘　　要：简要介绍了TRIP(transformation induced plasticity,相变诱导塑性)钢中残余奥氏体的形成及其微观组织形貌,综合阐述了残余奥氏体对TRIP钢性能的影响,并由此提出对TRIP钢进一步改善的途径。The formation and microstructure of retained austenite in TRIP steels were introduced. The influence of retained austenite on the mechanical properties of TRIP steels were studied. Furthermore, some ways were proposed to improve the properties of TRIP steels.

关 键 词：残余奥氏体 TRIP钢 机械性能
