Embodiment 1
[0018] A new type of nickel alloy containing: Mg: 0.001%, Mn: 0.12%, W: 0.45%, Co: 0.013%, Nb: 0.12%, Sn: 0.89%, Mo: 1.3%, Zn: 1.2% by weight. %, Ti: 1.5%, Fe: 0.51%, Y: 1.7%, Er: 0.73%, Sb: 0.007%, Cu: 37%, and the balance is Ni.
[0019] The manufacture process of a kind of novel nickel alloy preparation method is as follows:
[0020] (1) Melting: Weigh the raw materials of each component according to the ratio of the nickel alloy composition and put them into a graphite crucible, then place them in a vacuum induction furnace, vacuumize to 20Pa, then fill in an appropriate amount of argon, and then vacuumize and repeat. 8 times, and finally use argon as a protective gas for melting, the melting temperature is 1621°C, after the raw materials are completely melted, continue heating for 20 minutes to obtain a solution;
[0021] (2) Refining: control the temperature of the solution at 1690°C, add refining agent and fill the furnace with argon until the vacuum degree in the fur...
