The microstructure of Fe-0.4 C-2 Mn-4 Al experimental steel in as-cast and hot-rolled state was analyzed by SEM,XRD and EBSD.The mechanical properties of the experimental steel before and after rolling were studied.The results show that the TRIP steel contains a large amount of δ-ferrite in the microstructure before and after hot rolling,but the δ-ferrite morphology changes after hot rolling,and the fish bone shape is stretched into strips along the rolling direction.Shape,and the grain size has been refined.Consequently,the strength and elongation have been significantly improved,and the strong plastic product has reached 13.7 GPa·%.
