英文摘要	The influences of aging temperature and minor addition of Zr+Si on the damping property of Zn-22%Al alloy were investigated by dynamic mechanical analyzer (DMA) and microstructure observation. The results show that with the increase of aging temperature, the decomposition of super-saturated solid solution of Al (alpha' phase) is accelerated, resulting in increasing and coarsening of the lamellar structure, which will impair damping property. In addition, the damping property of Zn-22%Al alloy could be significantly improved by the minor addition of Zr+Si elements, which induced microstructure refinement and increase of interface. The dislocations induced by thermal mismatch between Si phase and matrix have little influence on the damping property of alloy, as the inter-diffusion of atoms makes dislocations decrease gradually.
