Abstract
This study aims to investigate the influence of iron content on the mechanical property of the recycle AA356 aluminium alloy. The recycle Alloys enriched with iron were prepared by casting and samples were chemically analyzed by mass spectrometry to confirm their composition. The alloy tixoability was evaluated by thermodynamic simulation via Thermocalc®, and then other alloys samples were prepared by partial melting. The samples were analysed metallurgically and mechanically. Through microstructural analysis, it was noted the presence of Fe-rich intermetallic in the alloys enriched with iron, which were not found in the alloy as received. The presence of these intermetallic contribute to improve the mechanical strength.
