Abstract
There are provided: an Ni-based alloy member including a γ' phase precipitation with 36 to 60 volume % and exhibiting a high durable temperature and good cold workability; a method for producing the member; an Ni-based alloy product to be used as a precursor of the member; and a method for producing the product. The Ni-based alloy product has a two-phase structure composed of a γ phase and a γ′ phase being incoherent to the γ phase, the incoherent γ′ phase being present at a ratio of 20 volume % or higher. The Ni-based alloy member produced by cold working the Ni-based alloy product and subsequently by conducting heat treatment comprises a γ phase and a γ′ phase being coherent to the γ phase, the coherent γ′ phase being present at a ratio of 36 to 60 volume %, and has a predetermined shape.
