Microstructure and compressive properties of multiprincipal component AlCoCrFeNiCx alloys

▶ In recent years, one kind of new alloys, high-entropy alloy with multiple principal elements in equimolar or near-equimolar ratios, has received more and more attentions due to its unique structure and excellent properties The most commonly used elements are Al, Ti, Cr, Fe, Co, Ni and Cu. These elements except Al are transition metal elements of the fourth period. The effects of nonmetallic carbon element on microstructure and properties of multiprincipal component AlCoCrFeNi alloy are investigated systematically in this paper.
