摘要
The efects of impurity element of Fe and microelements of Zn， Cr and Ti on the constituents，dispersoids， grain size， mechanical properties and formability of Al-l. 3Mg-l. 2Si-0. 6Cu-0. 3Mn aloy were investigated in the present work by analyzing microstructures, phase composition, mechanical tests. The resultsindicated that with the increase of Fe content, the insoluble constituents increased, and the mechanicalproperties and r15 of aloy sheets debased, which can be recovered by the addition of microelements Zn, Crand Ti. Al-1. 3Mg-1. 2Si-0. 6Cu-0. 3Mn alloy sheets in the T4 temper are difficult to strengthen with paint -bake treatment in automobile factory
