摘　　要：综述了孪生诱发塑性(TWIP)钢的研究现状及进展。重点介绍了各合金元素对TWIP效应的作用以及Fe-Mn-Si-Al、Fe-Mn-C、FevMn-C-Al3种不同成分系列TWIP钢的组织性能特点。总结了热处理工艺及应变条件对Fe-Mn-Si-Al系列TWIP钢孪生组织和力学性能的影响。简述了层错能对TWIP效应的重要影响作用以及几种测算层错能的方法。The present situation and progress in research on twinning induced plasticity （TWIP） steel are summarized. Based on the introduction of alloying elements for TWIP effect, the distinguishing features, such as microstructures and mechanical properties of the different compositions series of TWlP steels, i.e. Fe-Mn-Si-Al,Fe-Mn-C and Fe-Mn-C-Al are focused on. The effects of the annealing processes and deformation conditions on the microstructures as well as the mechanical properties of Fe-Mn-Si-Al system alloy are presented, The relationships between stacking fault energy and deformation mechanisms of TWIP steel are also illustrated, together with several methods for calculation or measurement of stacking fault energy.
