One of the main problems in the reuse of secondary hypereutectic Al–Si alloys is their contamination with iron. The review examines the influence of iron content on the mechanical properties and morphology of precipitated iron-containing phases, the effect on them of additions of additional chemical elements, methods of melt processing and temperature conditions of crystallization. As noted, the presence of iron, in addition to the negative effect, at some concentrations, has a positive effect on certain characteristics.
Key words: hypereutectic Al–Si alloys, iron-containing intermetallic compounds, primary silicon, morphology, mechanical properties.
