Abstract
A method for producing a dispersion strengthened material is presented. The method includes exposing a plurality of first metal particles to a suspension of dispersoid forming particles to form metal particles having the dispersoid forming particles thereon. The metal particles having the dispersoid forming particles there are subjected to an energy process to form a dispersion strengthened material. Also provided is a method of manufacturing a dispersion strengthened material or metal component that contains nano-sized dispersoids in a metal-based matrix.
Claims19
A method for producing a dispersion strengthened material, comprising:
- exposing a plurality of first metal particles comprising a first metallic composition to a suspension of dispersoid forming particles comprising a second metallic composition to form a plurality of metal particles having the dispersoid forming particles thereon, wherein the plurality of metal particles having the dispersoid forming particles thereon has an interior portion comprising the first metallic composition and an outer surface portion comprising the second metallic composition;
- and
- subjecting the plurality of metal particles having the dispersoid forming particles thereon to an energy process to form a dispersion strengthened material.
A method of manufacturing a dispersion strengthened metal component comprising nano-sized dispersoids dispersed in a metal-based matrix, comprising:
- covering a first metal powder comprising a first plurality of particles with a suspension of a dispersoid forming powder comprising a second plurality of particles to form a third metal powder comprising the first plurality of particles with the second plurality of particles thereon, wherein the first plurality of particles comprise a first metallic composition and a first mean particle size, wherein the dispersoid forming powder is suspended in a fluid carrier, wherein the second plurality of particles comprise a second metallic composition and a second mean particle size;
- and producing a component from the third metal powder using electron beam melting (EBM), direct selective laser melting (DSLM), selective laser melting (SLM), direct metal laser melting (DMLM), or directed energy deposition (DED).
The method of claim 18, wherein the first mean particle size is greater than the second mean particle size.
