Title:
METHOD FOR PREPARING ALLOY POWDER MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/228709
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing alloy powder material. Using the feature of an alloy solidification structure containing a matrix phase and an inert dispersed particle phase, the matrix phase is removed by reaction with an acid solution, so that the dispersed particle phase is separated to obtain the alloy powder material. The method is simple in process, and can prepare a variety of alloy powder materials with different morphologies including nanometer, submicrometer, micrometer and millimeter level, which has good application prospects in the fields including catalysis, powder metallurgy, and 3D printing.
