Effect of carbon alloying and heat treatment on the microstructure, mechanical properties, and tribological behaviour of a powder-metallurgy CoCrCuFeNi high-entropy alloy (HEA)
Introduction. Powder metallurgy high-entropy alloys (HEAs) of the CoCrCuFeNi system exhibit high strength but low ductility due to their ultrafine-grained structure and inhomogeneous distribution of the copper-rich phase. One approach to improve the balance of mechanical properties involves the microaddition of non-met...
