摘    要：采用自然时效、人工时效等热处理工艺研究了微量锆对Zn-22% Al合金阻尼性能(内耗)的影响。结果表明微量锆可提高Zn-22% Al合金的阻尼稳定性。运用电子显微镜和X射线衍射仪对未加锆和加锆的试样进行观察和分析，明确了锆减缓Zn-22% Al合金时效后阻尼性能(内耗)降低的原因。

Abstract: The effect of trace Zr on the damping capacity of Zn-22%Al alloy was studied by using natural ageing and artificial ageing. The results showed that trace Zr can improve the stability of damping capacity of the alloy. TEM observations and X-ray diffraction analyses for samples with or without Zr revealed the reasons of Zr slowing the reduction of damping capacity of Zn-22%Al after ageing.
