摘 要: 采用自然時效、人工時效等熱處理工藝研究了微量鋯對Zn-22% Al合金阻尼性能(內(nèi)耗)的影響。結果表明微量鋯可提高Zn-22% Al合金的阻尼穩(wěn)定性。運用電子顯微鏡和X射線衍射儀對未加鋯和加鋯的試樣進行觀察和分析，明確了鋯減緩Zn-22% Al合金時效后阻尼性能(內(nèi)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.
Key words: Zn-22%Al alloy Zr ageing damping capacity
