| 摘 要： | 研究了经过稀土、Ti变质处理和固溶自然时效处理的ZA27合金的阻尼特性，探讨了其阻尼机理，分析了变质处理及固溶自然时效处理对提高合金阻尼性能的作用。与铸态合金比较，经过变质、固溶自然时效处理后的合金，其阻尼性能有明显提高。阻尼性能提高是由于组织细化、界面增多以及位错增殖所致。

| Abstract: | ZA27 is zinc alloy which is modified by adding rear earth and Ti, solid solution and naturally aging. The damping properties of ZA27 and its mechanism are studied. The effect of modification, solid solution and natural aging treatment on damping properties is analyzed. Compare with cast alloy, the damping properties of ZA27 alloy treated by modification, solid solution and natural aging gets obvious improvement. It is because of microstructure refinement, an increase in boundaries and dislocation multiplication. |
