Abstract：
Automotive lightweight had brought broad development and application prospects for high manganese TWIP
steel. TWIP steel had developed for three generations since it was discovered in 1997. In the past 20 years, a large number
of researchers had conducted extensive studies on its mechanical properties, microstructure and processing technology. The
development of TWIP steel and the factors affecting TWIP effect were introduced, and the effects of microalloying and
different strain rates on the microstructure and properties of TWIP steel were summarized. The achievements of relevant
researches at home and abroad is summarized, and points out the contents to be further research direction.
