The current study explores the application of High Entropy Alloy (HEA) particles as reinforcements in an aluminium metal matrix, showcasing their potential utility in various mechanical, electrical, and electronic structural components. Successful synthesis of HEA particles was achieved through the mechanical alloying process. The composite was developed using the powder metallurgy route, which included cold pressing and sintering. The microstructures of the composite were investigated by FESEM coupled with EDS, and the mechanical properties were evaluated through room temperature hardness and compression tests. The experimental findings indicate a nearly even distribution and effective dispersion of HEA particles throughout the aluminium metal matrix. The results reveal that the incorporation of HEA particles into the aluminium matrix significantly improves the composite mechanical properties.
