The invention provides a preparation method of a nickel-based wrought superalloy wheel disk forging used at high temperature, in which the alloy has high content of solution strengthening elements W, Mo and strengthening phase γ' phase forming elements Al, Ti, Nb and γ′ phase content reaches 55-65%. In view of a series of technical problems caused by high γ′ phase to alloy smelting and forging, the high-temperature stress relief annealing, low-temperature stress relief annealing process of steel ingot and high temperature homogenizing annealing of steel bar were proposed by optimizing the thermal process of wheel disk forging and controlling the precipitation and dissolution of γ′ phase.

The present application relates to the field of superalloy, disclosing a method for internal stress regulation in superalloy disk forgings by pre-spinning. The method includes: Step S, determining a target revolution for regulating internal stress in the disk forgings, and determining a target deformation magnitude of plastic deformation required for regulating the internal stress by the pre-spinning of the disk forgings; and Step S, performing the pre-spinning of the disk forgings by the target revolution, monitoring a deformation magnitude of the disk forgings, and stopping the pre-spinning when a monitored deformation magnitude of the disk forgings reaches the target deformation magnitude.
