摘　　要： 利用Ｘ射线能谱分析和选区电子衍射技术对工业ＡｌＣｕＭｇＳｉ系锻铝合金中粗大夹杂物的成分和结构类型进行了研究 The compositions and structures of the impurity constituent phases in Al Cu Mg Si series forging Al alloys have been analyzed by means of X ray microanalysis and selected area electron diffraction. The results showed that the dominant constituent phases in this kind alloy are Al(Fe, Mn)Si which has primitive tetragonal crystal structure, Al 12 (Fe, Mn) 3Si which has body center cubic crystal structure and Cu 2FeAl 7 phase. Partial Fe atoms in the phases substituted by Mn atoms have been found to occur, which results in unvariation of the constituent phases.
