  • Patent number: 12031190
    Abstract: A method for producing a Ni- or Ti-based alloy product includes preliminarily processing a hot working material of a Ni- or Ti-based alloy after hot working into a predetermined shape; heating and holding the material at a solution treatment temperature to obtain a material held in a heated state; and cooling the material to obtain a solution-treated material. The cooling step includes placing a flow path-forming member having a space for forming a flow path for a fluid on a surface of the material held in a heated state to form a fluid flow path defined by the surface of the material held in a heated state and an inner surface of the space of the flow path-forming member; and allowing a fluid to flow in the fluid flow path so that the fluid in the flow path locally cools a part of the surface of the material.
