摘要：

In this paper, a novel method of severe plastic deformation (SPD), i.e., forging-bending repeated de-formation process, was proposed to prepare AZ31 magnesium alloy sheets. The effects of the new process on the equivalent strain, flow rate, microstructure, and hardness at different passes were investigated by finite element method (FEM), electron backscatter diffraction (EBSD) and Zwick/roll hardness tester. The results showed that the effective strain and flow velocity increased with the increase of the pass. Due to the transition path, the shear deformation was sufficient at each position an...
