A nickel-based superalloy ring and a method of forging the same

Abstract

The application provides a nickel-based high-temperature alloy ring piece and a forging method thereof, and relates to the technical field of metal forging, and comprises the following steps: step 1) one-fire heating and heat preservation are performed on a nickel-based high-temperature alloy blank, and then upsetting punching and ring rolling are sequentially performed to obtain a ring blank; wherein the nickel-based high-temperature alloy blank contains La elements; step 2) two-fire forging is performed on the ring blank, solid solution treatment is performed after heat preservation treatment, and a nickel-based high-temperature alloy ring piece is obtained after cooling; wherein the temperature of the two-fire forging is 1130-1150 DEG C. Through the addition of rare earth elements and the strict control of the forging temperature, the problems of uneven structure, mixed crystal and the intensification of crack initiation of the carbon clusters of the nickel-based high-temperature alloy ring piece are solved, and the mechanical properties of the nickel-based high-temperature alloy forging are significantly improved. In the industry, a higher-quality nickel-based high-temperature alloy ring piece product is provided.
