Title:
METHOD FOR PRODUCING NICKEL-BASED ALLOY PRODUCT OR TITANIUM-BASED ALLOY PRODUCT
Document Type and Number:
WIPO Patent Application WO/2021/106998
Kind Code:
A1
Abstract:
Provided is a method for producing a Ni-based or Ti alloy product, the method being capable of locally increasing the cooling rate and performing effective cooling. This method for producing a Ni-based alloy or Ti alloy product includes a cooling step in which a hot-worked material, which is made of a Ni alloy or Ti alloy and has been subjected to hot working, is processed in a predetermined shape in advance and heated and retained at a solid-solution treatment temperature to obtain a heat-retention material, and the heat-retention material is cooled to obtain a solid-solution-treated material, wherein in the cooling step, a flow path forming member having a space for forming a fluid flow path is arranged on the surface of the heat-retention material to form the fluid flow path formed by the surface of the heat-retention material and the inner surface of the space of the flow path forming member, and a fluid is made to flow through the fluid flow path formed between the flow path forming member and the heat-retention material and the fluid in the flow path locally cools the surface portion of the heat-retention material.
