摘　　要：铁基形状记忆合金的形状记忆效应和超弹性取决于合金的马氏体相变特征,掌握铁基合金的马氏体相变规律是开发和优化铁基形状记忆合金的前提。根据马氏体相变类型将目前发现的铁基形状记忆合金分成3类:Fe-Mn-Si系,Fe-Ni-Co系和Fe-Pt/Fe-Pd系,分别阐述了3类铁基形状记忆合金马氏体相变的研究进展,总结了铁基合金形状记忆效应的不同机理和影响马氏体相变特征的各种因素,探讨了开发新型铁基形状记忆合金的需要关注的方向。shape memory effect and superelasticity of Fe-based alloys depend on the natures of martensitic transformation in iron-based alloy. Understanding of martensitic transformation in iron-based alloys is important for development and optimization of Fe-based shape memory alloys. Based on the different features of martensitic transformation, Fe-based shape memory alloys are divided into three categories, including Fe-Mn-Si, Fe-Ni-Co and Fe-Pt/Fe-Pd system. Recent development of martensitic transformation in these three types of Fe-based shape memory alloys are reviewed in this manuscript, respectively. The different mechanism with which shape memory effects are associated and the factors to influence martensitic transformation are summarized. The prospect for developing new iron-based shape memory alloys is also discussed.
