Popis: Solute Fe and Mn concentration in aluminum alloys were estimated with the phenol filtrate analysis method. This method consists of extraction of intermetallic compounds by dissolving aluminum matrix with phenol and direct analysis of the filtrate. It was found that solute Fe and Mn concentration is well estimated by selecting an appropriate filtration procedure. As the results, estimated solute Fe and Mn concentration showed a good correlation with the specific resistivity. The degree of contribution of Fe and Mn to the specific resistivity also agreed well with the previous work. The solid solubility curves of both Al–Fe and Al–Mn binary systems were determined based on the method. The obtained solubility curves were also well consistent with the previous results. The phenol filtrate analysis is a useful method to measure solute concentration in Al directly without disturbance by coexisting elements and dislocations.
