The microstructure and the mechanical properties of AZ80+Ce magnesium alloy wheel hub during forming pratess were analyzed and researched. The results show that in the process of forming wheel hub, the dynamic recrystallization occurs in each plastic deformation. The grain size decreases gradually with the increase of deformation times. The rare earth element Ce as the nucleating center promotes the nucleation and prevents further growth of the grains, so as to refine the grain of the alloy. The tensile str...
