The two-stage deformation was processed to ZM21alloy as cast at different parameter condition, and structure evolution and mechanical property was analyzed. The results indicate that the grain of ZM21 alloy as cast will be fined by the two-stage extrusion deformation, and its size can decreases from about 100μm to 15.6μm. The strength of ZM21 alloy can be raised by the two-stage deformation, up to 261.7MPa, At the same time, the prolongation rate is more than 16% by the two-stage deformation.
