Abstract:

High entropy alloy (HEA) Cu29Zr32Ti15Al5Ni19 consisting of two solid solution phases and bulk metallic glass (HE-BMG) with the same composition were successfully prepared separately by casting in a copper mold. The result indicates that the alloy has high glass forming ability. The compressive strength of as cast HEA Cu29Zr32Ti15Al5Ni19 is 1127MPa. HEA Cu29Zr32Ti15Al5Ni19 shows good tempering resistance. The hardness of Cu29Zr32Ti15Al5Ni19 remains 826HV after treated at 750℃ for two hours.
