Title:
ODS ALLOY POWDER, METHOD FOR PRODUCING THE SAME BY MEANS OF PLASMA TREATMENT, AND USE THEREOF
Document Type and Number:
Japanese Patent JP2022192063
Kind Code:
A
Abstract:
To provide a method for producing an ODS alloy powder having optimized characteristics of a composition and/or microstructure.SOLUTION: A method for producing a reinforced alloy powder (ODS alloy) in which the grains forming the particles of the powder comprise a metal matrix, in the volume of which crystalline oxide particles are dispersed, includes the following steps: i) preparing a powder mixture to be milled comprising a master alloy for forming the metal matrix and an additional powder comprising at least one intermediate compound intended to incorporate atoms for forming the dispersed oxide particles; ii) milling the powder mixture according to a mechanical synthesis process for making a precursor powder; iii) exposing the precursor powder to a thermal plasma generated by a plasma torch comprising a plasma gas, in order to obtain the reinforced alloy powder.SELECTED DRAWING: Figure 3A
