Al-Fe-V-Si alloy and composites from it were prepared by a powder metallurgy (PM) route as well as by mechanical alloying (MA). Globular particles referred to as alpha-Al-13 consisted of a quaternary silicide of Al-x(FeV)(y)Si and alpha-AlFeSi diminished after ball milling and grows slightly during the fabrication process. Whereas, the particle in the PM samples grew extensively. For PM samples, the high temperature mechanical strength of the composite is slightly higher than for the unreinforced alloy.
