摘要
本文对铸造锌铝合金7A27在室温下的力学性能和低周疲劳性能进行了测试，得到了ZA27合金的应变疲劳性能参数，循环应力一应变曲线，并对7A27合金疲劳试件断口进行了分析，结果表明：铸造锌铝合金ZA27在循环载荷作用下表现为循环软化，断口表现为准解理。
The tensin properties and low cycle fatigue properties of alloy ZA27 at ambient temperature were studied in the paper The cyclic stress-strain curve strain fatigue properties of alloy ZA2 7 .are obtained.The result show that,the cyclic stress-strain curve of alloy ZA2 7 laid under the morotonic ones,thus cyclic softening character was displayed.The fracture surface analysis indicated that the typical morphology was intercrystalline failure.
