Abstract

Metal matrix composites (MMCs) reinforced with high entropy alloy particulates (HEAps) are a new class of metal-matrix composites that have the promise to meet the demanding requirements of nascent technological applications. Their desirability has been predicated on their favourable combinations of toughness, strength, ductility, and improved workability, which are acknowledged limitations of ceramic-reinforced MMCs. The superior wettability obtained between the metal matrix and the HEAps reinforcement, as well as the HEAps' intrinsic ductility and hardness, have been linked to their improved properties over conventional MMCs. This review discusses the applicability of high entropy alloys as alternatives to ceramic materials for reinforcement of metal matrix composites– Al, Cu, Mg, Ti, and W. The mechanical, corrosion, wear, and thermal properties of MMCs reinforced with high entropy alloy particles (HEAps) were discussed. Their fabrication characteristics and interfacial reactions are also assessed. This report highlights the performance benefits and certain issues associated with HEAps reinforcement application in MMCs. Finally, potential future research directions in this field are suggested.
