Title:
METHOD FOR PRODUCING METAL MEMBER AND METAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2024/053418
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing a metal member capable of producing a metal member containing not only a second component but also a third component. [Solution] A metal material comprising a compound, alloy, or non-equilibrium alloy having a second component that is mutually insoluble with a first component and a third component that is mutually soluble with the first component and mutually soluble with the second component is prepared. A metal bath having a first component and a third component is prepared. The metal bath is controlled to a temperature lower than the minimum value of the liquidus temperature within the composition variation range from the composition of the metal material to the composition where the third component in the metal material decreases and equilibrium with the metal bath is reached. By immersing the metal material in the temperature-controlled metal bath, the third component contained in the metal material is selectively eluted out into the metal bath, and a metal member having the second component and the third component is obtained.
