The formation of (Al 8 Fe 2 Si, Al 13 Fe 4 ) phases from Al-Fe-Si system by TE mode

Abstract

This work prepared Al 8 Fe 2 Si, Al 13 Fe 4 mixed sample by ball milling and thermal explosion techniques applying Al, Fe and Si powders as precursors. Thermal combustion of powder mixes of composition 24, 37 Al+ 50, 36 Fe + 25, 27 Si in mass reveals production of several binary and ternary intermetallic phases such: A1 13 Fe 4 and Al 8 Fe 2 Si. Synthesis conditions were optimized to fabricate these phases having many potential applications.
