Al-Mg-Si合金拉伸断口研究

An Investigation on Tensile Fracture of Al-Mg-Si Alloys

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 compositions were aged and tensile strength were measured. Scaning electron microscope was used to study the appearance of a fractoographs. The results show that the composition and ageing treatment have different effects on the tensile fractures.
