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.
