摘　　要：概述了TRIP钢的发展概况、相变诱发塑性的影响因素以及TRIP钢的分类等。从相变驱动力、M_s点与M_d点的物理意义以及马氏体相变诱发塑性等方面论述了形变诱发马氏体转变的热力学条件。阐述了TRIP钢中合金元素的作用以及目前所广泛研究的中锰TRIP钢。认为热轧TRIP钢如果能在我国实现在线生产,将会减少轧后热处理环节,生产率提高,经济效益显著。The development of TRIP steel,influential factors of transformation induced plasticity and the classification of TRIP steel w ere summarized. The thermodynamics condition of deformation induced martensite transformation w as explained based on transformation driving force,the physical meaning of M s and M d and transformation induced plasticity of martensite. The effect of alloy elements on TRIP steel and medium-M n TRIP steels w ere clarified. It is proposed that if the hot rolled TRIP steels could be realized on-line application in our country,heat treatment process after hot rolling w ould be shortened,and cold rolled and annealed TRIP steels w ould be substituted. The productivity w ould be enhanced and the economic benefit w ould be remarkable.
