| Zusammenfassung: | The invention provides a heat treatment method for Nimonic101 nickel-based alloy. The heat treatment method for the Nimonic101 nickel-based alloy comprises the following steps that (1) solid solution heat treatment is conducted on a Nimonic101 nickel-based alloy forged piece, and the Nimonic101 nickel-based alloy forged piece is discharged out of a furnace and air cooled; (2) intermediate heat treatment is conducted on the air-cooled Nimonic101 nickel-based alloy forged piece at the temperature of 1020-1080 DEG C, heat preservation is conducted for 8-16 hours, and then the Nimonic101 nickel-based alloy forged piece is discharged out of the furnace and air cooled; and (3) aging heat treatment is conducted on the air-cooled Nimonic101 nickel-based alloy forged piece, and then the Nimonic101 nickel-based alloy forged piece is discharged out of the furnace and air cooled, so that the Nimonic101 nickel-based alloy is prepared. Compared with heat treatment methods which are frequently used at present, the heat trea |
