Abstract：In this paper, the stamping performance of AZ31 magnesium alloy plate after asynchronous rolling with large deformation of single pass was studied.The bending strength ratio, plastic strain ratio, strain hardening index n and lug parameter data of stamping performance index were analyzed.It is concluded that with the grain refinement, the cup protrusion value decreases gradually, the ear-making phenomenon becomes more and more serious, and the stamping performance of sheet metal decreases.
