Abstract

Disclosed herein are metal matrix composites and methods of making and use thereof. For example, disclosed herein are methods of making a metal matrix composite comprising a metal matrix reinforced by a high entropy alloy. The methods comprise 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. The methods further comprise compacting the powder mixture to form a pellet and 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. The methods further comprise subjecting the molten mixture to an ultrasonic treatment and casting the ultrasonic treated mixture to form the metal matrix composite.
