Abstract

Provided is a method for producing a Ni- or Ti-based alloy product, the method capable of reliably locally cooling and effectively cooling. The method includes the steps: heating and holding a hot working material of a Ni- or Ti-based alloy after hot forging or hot ring rolling at a solution treatment temperature to obtain a material held in a heated state, and cooling the material held in a heated state to obtain a solution-treated material. The cooling step includes carrying out local cooling by contacting a cooling member with a part of a surface of the material held in a heated state.

Claims (7)

1. A method for producing a nickel-based alloy product or a titanium-based alloy product, comprising:

a heating and holding step of heating and holding a hot working material of a nickel-based alloy or a titanium-based alloy after hot forging or hot ring rolling at a solution treatment temperature to obtain a material held in a heated state; and

a cooling step of cooling the material held in a heated state to obtain a solution-treated material,

wherein the cooling step comprises carrying out local cooling by contacting a cooling member with a part of a surface of the material held in a heated state.

2. The method for producing a nickel-based alloy product or a titanium-based alloy product according to claim 1 , wherein the cooling member is worked into a shape in which a contact surface of the cooling member in contact with the part of the surface of the material held in a heated state matches a shape of the part to be locally cooled of the material held in a heated state.

3. The method for producing a nickel-based alloy product or a titanium-based alloy product according to claim 1 , wherein the local cooling is carried out by contacting the cooling member with the part of the surface of the material held in a heated state at a surface pressure of at least 0.01 MPa.

4. The method for producing a nickel-based alloy product or a titanium-based alloy product according to claim 1 , wherein an entirety of the material held in a heated state is uniformly cooled in the cooling step.
