Title:
POWDER, METAL COMPONENT, ELECTRICAL CONTACT, AND METHOD FOR PRODUCING POWDER
Document Type and Number:
WIPO Patent Application WO/2023/238285
Kind Code:
A1
Abstract:
This powder is an aggregate of a plurality of particles containing metal elements. The plurality of particles each comprise a matrix, and a plurality of precipitates dispersed in the matrix. The matrix contains a first component, and the plurality of precipitates each contain a second component. The first component and the second component are a combination that has a two-liquid phase separation region in a phase diagram. The content ratio of the first component and the second component corresponds to the two-liquid phase separation region. The standard error of the first component content in the plurality of particles is not more than 1.2 in terms of mass, and the standard error of the second component content in the plurality of particles is not more than 1.2 in terms of mass.
