摘要：

The effects of annealing process on mechanical properties and the stability of retained austenite of third generation of AHSS of cold-rolled low-carbon medium-manganese TRIP steels were investigated. The results show that the mechanical properties are significantly influenced by intercritical annealing temperature and soaking time. When the samples of 6.72%Mn-TRIP steel are annealed at approximately 590 for 18 h, the tensile strength is 815 MPa and the elongation is 38%, the UTS×TE values in excess of 30 GPa·% can be obtained. During the intercritical soaking time, C and Mn atoms in the martensite have partitioned into retained austenite, thereby, the retained austenite can be stabilized at room temperature. Due to the combination of the retained austenite, martensitic and recrystallization ferrite, that the remarkable combinations of strength and ductility are obtained.
