Abstract: AZ31 magnesium alloy plates were fabricated by friction stir processing(FSP), and the microstructure and mecha-nical properties of the processed region were studied. The results showed that the average grain size increased as a result of increasing rotation speed under the same travelling speed. After FSP, grain size and texture affect the mechanical properties of AZ31 magnesium alloy significantly, the twin deformation would be more likely to occur with greater average grain size. Texture type mainly included basal plane texture and fiber texture, while the yield strength was lower when basal plane texture was in the soft orientation, but fiber texture would weaken the influence of basal plane texture of mechanical properties.
