摘　　要：从化学成分、强韧化机制和热处理工艺3个方面综述了国内外中锰钢的研究现状。分析总结了Mn、C、Al等元素对中锰钢组织性能的影响;针对中锰钢变形过程中强韧化机制,着重介绍了相变诱发塑性(TRIP)效应及其影响因素;中锰钢的组织和性能与热处理工艺紧密相关,重点介绍了奥氏体逆转变(ART)、淬火+回火(Q&T)、淬火配分(Q&P)等热处理工艺及其对组织性能的影响。最后展望了中锰钢未来研究的方向。Research status of medium-Mn steels at home and abroad were reviewed from three aspects:chemical composition,strengthening and toughening mechanism,and heat treatment processes.The effects of elements such as Mn,C,and Al on the microstructure and properties of medium-Mn steels were analyzed and summarized.Regarding the strengthening and toughening mechanism during the deformation of medium-Mn steels,the transformation-induced plasticity(TRIP)effect and its influencing factors were emphasized.Considering that the microstructure and properties of medium-Mn steels were closely related to heat treatment processes,the heat treatment processes such as austenite reverse transformation(ART),quenching and tempering(Q&T),quenching and partitioning(Q&P),and their effects on the microstructure and properties were introduced in detail.Finally,the future research directions of medium-Mn steels was prospected.
