Abstract: In this paper,the development history of titanium microalloyed high strength steel is briefly reviewed. The research and development status of titanium microalloyed high strength steel expounded in detail,more attention is paid to the precipitation behavior of nano-carbide （stain-induced precipitation and interphase precipitation） in titanium microalloyed high Strength Steel above 700 MPa,and the development trend of titanium microalloying technology is also analyzed,aiming at perfecting physical metallurgy theory of Ti microalloying high strength steel and providing some guidance for the development and industrial application of titanium microalloying high strength steel.
