| Abstract: | Transformation induced plasticity （TRIP） effect causes the occurrence of martensitic transformation in retained austenite during plastic deformation,TRIP steel with both high strength and excellent shaping ability has been one of the hot issues in current automobile steel research. The research development of TRIP steel is briefly discussed in this paper,elaborating the effects of the composition and microstructure,size and volume fraction of retained austenite on the strength and ductility of the steel. The industrial application and trends of development of the TRIP steel at home and abroad are also discussed. |
