Claim 3:
4. The method for preparing a copper alloy according to claim 3, wherein the forged Ni-base superalloy is prepared according to the following steps: smelting an alloy ingot by the vacuum melting+electroslag remelting process, after homogenizing the alloy ingot at 1250° C.×1 to 4 h, forming by isothermal forging at 1000° C. to 1050° C., with a deformation of 80% to 90%; afterwards, holding at 800° C. for 8 to 16 hours, and tempering 1 to 2 hours at 300° C. to 400° C. after water quenching.
