Abstract

A method of producing a Ni-based superalloy is provided. A hot working material is used and consisting of a specific composition and has a solvus temperature of a γ' phase of 1050° C. or more. The method includes: performing heating in a temperature of 980° C. to 1050° C. with an upper limit of −30° C. from the solvus temperature of the γ′ phase, for 10 hours or longer; and performing hot working on the material at a working speed of a strain rate of 2.0/second or more in the above temperature range.
