Mechanism of superplasticity of high-strength low-alloy quenched and tempered steel in the two-phase region is proposed through analysis of tensile stress-strain characteristics of the 10CrNi3MoV steel at superplastic temperature. Microstructure and fracture behavior of different degrees of deformation and numerical simulation of the distribution of plastic strain fields were analyzed. Results showed that the austenite phase with low yield stress around the ferrite phase with high yield stress… CONTINUE READING
