Abstract
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.
