对两种化学成分不同的Al-Mg-Si合金进行了时效处理,测定了合金在不同时效条件下的拉伸性能,采用扫描电镜对拉伸断口进行了系统研究。结果表明,化学成分和时效处理对合金拉伸断口影响不同。
Two kinds of Al-Mg-Si alloys with different chemical compositions were aged, the tensile properties of the alloy under different aging conditions were measured, and the tensile fracture was systematically studied by scanning electron microscopy. The results show that chemical composition and aging treatment have different effects on tensile fracture of alloy.
