Method for eliminating residual stress of alloy part

The invention belongs to the technical field of residual stress elimination, and particularly relates to an alloy part residual stress elimination method. The invention provides a method for eliminating residual stress of an alloy part. The method comprises the following steps: carrying out first vibration aging treatment on an alloy part blank; the alloy part blank subjected to the first vibration aging treatment is subjected to finish machining, and an alloy part is obtained; and the alloy part is subjected to second vibration aging treatment. The overall residual stress of the alloy part blank can be homogenized through the first vibration aging treatment, and the situation that the residual stress in the alloy part blank and the residual stress generated in the finish machining process are superposed to form higher residual stress is avoided; and through the second vibration aging treatment, the residual stress generated by finish machining of the alloy part can be effectively reduced.
