摘要

对ＺＡ２７合金和ＺＣｕＳｎ１０Ｐ１在室温下的力学性能和低周疲劳性能进行了测试，得到了两种材料在恒应变幅试验下的循环应力－应变曲线。并对两种材料的疲劳试件断口进行了分析，结果表明：ＺＡ２７合金表现为循环软化，疲劳断口为准解理。ＺＣｕＳｎ１０Ｐ１表现为循环硬化，疲劳断口以韧窝和疲劳辉纹为主。

Abstract

The mechanical properties and low cyclic fatigue properties of alloy ZA27 and ZCuSn10P1 at ambient temperature were studied. Their cyclic stressstrain curves are obtained in constant strain amplitude condition. The results showed that the cyclic softening character with quasicleavage fatigue fracture for ZA27 alloy appeared while the cyclic hardening character with dimple and stripe fatigue fracture for ZCuSn10P1 alloy occured.
