Abstract:

High entropy alloy (HEA) is a new class of alloy that has a different alloy design concept over the conventional dilute alloys. In this alloy, the alloying elements have an equi-atomic ratio that helps to increase the entropy of the alloy to stabilize the simple solid solution (BCC, FCC and HCP) over the intermetallics. The stabilization of solid solution improves the paradoxial properties such as strength and toughness. High thermal stability, excellent creep and fatigue properties, outstanding corrosion resistance are the attractive features of HEA. Recently, the HEA is explored as a matrix or particle in the metal matrix composites. Research studies on HEA based composites are plenty and scattered. In this work, we attempt to collate essential information in the HEA based composites. The overview covers (1) processing techniques, (2) microstructure characterization and (3) the mechanical properties in detail. A short note on the potential applications of HEA based composites is also proposed.
