Development of the theories to optimizing properties of TRIP steels, such as crystallography, thermodynamics, kinetics and TRIP effect of martensite transformation, are introduced. WLC and B-M crystallography, O-C thermodynamics, K-M and O-C kinetics are described. G-J effect and Magee effect, which are used to explain TRIP effect, are explained. Theoretical study progress of TRIP steels are summarized. At last, the existing problems of theoretical study is pointed out, and the perspective of the future research are proposed.%阐述了优化TRIP(相变诱导塑性)钢所需的马氏体相变晶体学、热力学、动力学和TRIP效应等基本理论,重点介绍了WLR和B-M晶体学、O-C热力学、K-M和O-C动力学以及与TRIP效应相关的G-J、Magee机制.概述了TRIP钢的理论的研究进展,提出了目前理论研究存在的问题和研究方向.
