1. A method of making a metal matrix composite comprising a metal matrix reinforced by a high entropy alloy, the method comprising:
mixing a first powder and a second powder to form a powder mixture, wherein the first powder comprises a plurality of particles comprising a metal and the second powder comprises a plurality of particles comprising a high entropy alloy, wherein the metal is pure aluminum or an aluminum alloy;
compacting the powder mixture to form a pellet;
adding the pellet to a molten metal, the molten metal comprising the metal in a molten state, thereby melting the pellet to form a molten mixture;
subjecting the molten mixture to an ultrasonic treatment, thereby forming an ultrasonic treated mixture; and
casting the ultrasonic treated mixture to form the metal matrix composite, the metal matrix composite having a final weight;
wherein the high entropy alloy is provided in an amount of from 1-30 wt. % relative to the final weight of the metal matrix composite.
