The effect of iron content ranging from 0.1 to 0.5 mass% on the occurrence of Al–Fe–Si intermetallic compound particles in a 6063 aluminum alloy was investigated in the as-cast state using X-ray diffraction and transmission electron microscopy (TEM). The compound particles were extracted from the ingot by the thermal phenol method. In the 0.1% Fe alloy, monoclinic β, hexagonal α' and simple cubic α phases were observed. When the iron content increased to 0.2%, the relative frequency of the β phase sharply increased to about 80% and became the main phase. In contrast, in the 0.3%Fe alloy with additional iron, the relative frequency of the β phase decreased to about 20%, while that of the α phase increased to about 70%. When the iron content was 0.5% above the specified iron content, this tendency became remarkable, and no β phase was observed. As mentioned above, it is found that a slight change in the iron content of this alloy causes considerable changes in the relative frequency of the Al–Fe–Si intermetallic phase.
