摘要
Al-Mg-Si alloys(6000 series)exhibit a promising prospect as conductive materials due to their high specific strength,high electrical conductivity,excellent formability,good weldability,corrosion resistance and relatively low cost[1-3].These optimum properties are largely attributed to the formation of small-sized,coherent or semi-coherent and metastable phases brought by aging treatment[1,4].
