In this study, the effects of iron content and sintering temperature on the microstructure and hardness of Al-Fe-based alloys were investigated. Samples were produced via the powder metallurgy method and sintered at 610 °C and 640 °C. Scanning electron microscopy (SEM) and Brinell hardness tests were conducted for characterization. Microstructural analyses revealed that some iron particles remained unreacted at 610 °C, while at 640 °C, the formation and homogenization of Al₃Fe intermetallic phases were more evident. The hardness results showed that both increasing Fe content and higher sintering temperature contributed to improved Brinell hardness. These findings suggest that optimizing the sintering temperature and alloy composition can significantly enhance the mechanical performance of Al-Fe alloys.
