Abstract：Aluminum iron master alloy is one of the important raw materials in the production of aluminum alloys. It is necessary to analyze the precipitation characteristics of intermetallic compounds in equilibrium state, which can provide reference for the adjustment and control of chemical composition and microstructure of cast or wrought aluminum alloys. The compound phases in the incoming raw material AlFe10 master alloy were analyzed using physical metallographic methods. The morphology, distribution, and content of the compound phases were detected using metallographic microscopy (OM) and the accompanying ProImaging metallographic image analysis software. The micro composition analysis of the compound phase was performed using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results showed that the AlFe10 intermediate alloy contained long-strip or small FeAl3 phase with an area of approximately 27.6%. The peeling site contained non-metallic inclusions of C, O, Al, Si and Cl with an area of approximately 3.8%. No elemental Fe was found in the detection area.
