Method for cooperatively regulating and controlling structure performance and residual stress of high-temperature alloy disc forge piece

The invention relates to the technical field of high-temperature alloy machining, in particular to a method for cooperatively regulating and controlling the structure performance and residual stress of a high-temperature alloy disc forge piece. The method for cooperatively regulating and controlling the structure property and the residual stress of the high-temperature alloy disc forging comprises the following steps: carrying out solid solution heat treatment on the high-temperature alloy disc forging, and then carrying out air cooling; in the air cooling, in the process of changing from Ts to (Ts-20 DEG C) to (Ts-100 DEG C), the cooling rate is controlled to be 5-50 DEG C/min; in the process of changing from (Ts-20 DEG C) to (Ts-100 DEG C) to (Ts-200 DEG C) to (Ts-500 DEG C), the cooling rate is controlled to be 50-250 DEG C/min; in the process of changing from (Ts-200 DEG C) to (Ts-500 DEG C) to room temperature, the cooling rate is controlled to be 20-100 DEG C/min. According to the method, the mode of co
