Abstract: The compositionns and structures of the impurity constituent phases in Ai-Cu-Mg-Si series forging Al aiioys 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 hs primitive tetragonal crystal structure,Al₁₂ (Fe,Mn)₃Si which has body center cubic crystal structure and Cu₂FeAl₇ phases. Partial Fe atoms in the phases substituled by Mn atoms have been found to occur,which results in unvariation of the constituent phases.
