The alloying elements distribution in hypoeutectical-7%si alloys in the progress of complex physical-chemical melt treatment

The regularities of the complex physicochemical melt treatment influence on the distribution of chemical elements between phases in hypoeutectic Al-7%Si alloysare established. The data of spectral analysis correlate well with the results of microstructural, X-ray analysis and mechanical testing of alloys: AlSiSr type intermetallic compounds are formed, phases based on FeSiAl5 and Fe2SiAl3 intermetallic phases alloyed with strontium and scandium, as well as the π phase upon strontium-scandium complexmicroalloying of Al-7%Si alloys etc. Ultimate deformation of the alloy does not lead to a signifi cant redistribution of alloying elements.
