EFFECTS OF TRACE Zr ON FATIGUE CRACK GROWTH RATE OF HIGH DAMPING Zn-Al ALLOY
（Department of Materials Science and Engineering,Central South University of Technology, Changsha 410083）
Abstract:The fatigue crack growth rate of a high damping Zn-Al eutectoid alloy containing trace Zr and a Zn-Al eutectoid alloy has been measured. The Paris expression of both alloys has been obtained from the experimental results. The experimental results show that the lower fatigue crack growth rate of the alloy containing Zr is related to its higher internal friction value.
Key words: Zr Zn-Al alloy fatigue crack growth rate internal friction
