【 摘 要 】
AZ31 base alloy were subjected to friction stir processing (FSP) with different rotating speed. The effect of FSP on the microstructure, mechanical properties and damping capacities of AZ31 alloy was discussed in this paper. The fine and equiaxed grains were obtained in the SZ for FSPed samples with the rotating speed from 1300rpm to 1700rpm with the average grain size of 11.82μm, 12.93μm and 14.50μm, respectively. The FSPed samples had higher ductility and damping capacities compared with the AZ31 base alloy. The ductility and damping values Q0-1(=10-4) and QH-1(=10-3) of 1500rpm FSPed sample were increased by 121.44%, 5.02% and 7.49%, respectively.
