摘要：The effects of C element on the microstructure and properties of CoCrFeNiCx high entropy alloys (x denoted the atomic fraction of C element at 0, 0.05, 0.1, 0.2, 0.3, and 0.5) were investigated. The equal molar CoCrFeNi alloy with FCC structure exhibits high ductility but weak strength. With the addition of C element, both the hardness and strength of the CoCrFeNiCx high entropy alloys increase as well as the wear resistance. The solution strengthening and the formation of hard carbide phase are the main factor for the improved strength, hardness and wear resistance of CoCrFeNiCx high entropy alloys.
