Abstract
The article presents the results of thermodynamic diagrammatic analysis of the Al-Si-Mn-Fe metal system as characterizing the final composition of the manganese-containing complex ferroalloy. By the method of thermodynamic diagrammatic analysis, the phase equilibrium of the Al-Si-Mn-Fe metal system was constructed, and the coexisting phases in the alloy were determined. Experimental samples of the aluminosilicomanganese alloy were studied on an Empyrean Malvern Panalytical X-ray diffractometer (XRD), where the presence of phases in the form of an intermetallic compound was determined - MnSi, Mn15Si26, Al2Fe3Si4, Al5Fe2, FeSi and structurally free silicon.
