摘要

In order to study the feasibility and machinability of AZ31 Mg alloy prepared by extrusion-continuous shear (ECS) process, the numerical simulation and experimental methods are combined in this paper. The flow evolution of ECS process of AZ31 Mg alloy was simulated and analyzed by finite element analysis software, and the microstructure evolution and the mechanical behavior of different regions of AZ31 Mg alloy were characterized. The results show that the effective stress field and effective strain field of AZ31 Mg alloy show a large value in the CS zone, and the deformation is large. The hardness of the formed Mg alloy is about 74 HV. The grains of Mg alloy prepared by ECS process are significantly refined. The texture strength of Mg alloy fluctuates with the recrystallization during cooling.
