The different chemical composition of silicon and manganese as well as different re-tained austenite fraction ranged from 4to 101163326174f the high strength and high elon-gation steels were studied in the paper.The dislocations and carbon concentration in retained austenite were observed by a transmission electron microscope and an electric probe analyzer,respectively.The experimental results showed that silicon and manganese are two fundamental alloying elements to stabilize austenite effectively but retaining austenite in different mechanis-↑ms.Meanwhile,the cooling processing played an important role in controlling the fraction of retained austenite of the hot-rolled high strength and high plasticity steels.
