摘要(Abstract)：

通过拉伸、剥落腐蚀、晶间腐蚀等实验和XRD、SEM、TEM等方法,研究了单级时效和形变热处理对一种Al-Mg-Si合金(Mg/Si=1.15)的力学性能和耐蚀性能的影响。结果表明:经过形变热处理Al-Mg-Si合金(Mg/Si=1.15)抗拉强度和屈服强度分别为395 MPa和365 MPa,比经过单级时效处理(抗拉强度为339 MPa,屈服强度为280 MPa)分别高了17%和30%;经过形变热处理Al-Mg-Si合金(Mg/Si=1.15)晶间腐蚀敏感性低于单级时效处理的,但其综合性能比经过单级时效处理的性能好。

关键词(KeyWords)： Al-Mg-Si合金(Mg/Si=1.15);时效;形变热处理;力学性能;耐蚀性能
