Summary:After aluminium alloys were dissolved with boiling phenol, intermetallic compounds having an insoluble character were separated from the matrix by filtration. The contents of the intermetallic compounds and the solid solutions were determined by inductively coupled plasma atomic-emission spectrometry. Al-Mg and Al-Mg-Si alloys were assayed. The total values of the intermetallic compounds and the solid solutions in each sample were almost equal to the contents value of a bulk. We have compared most of iron in Al-Mg sample alloys with the tensile strength, yield stress and elongation. On the whole, a decrease in amounts of iron in intermetallic compounds tends to decrease both strength and yield stress.
