Title:
MANUFACTURING OF OXIDE-DISPERSION STRENGTHENED ALLOYS BY LIQUID METALLURGY
Document Type and Number:
WIPO Patent Application WO/2022/225622
Kind Code:
A3
Abstract:
Provided herein is a method of producing an oxide-dispersion strengthened (ODS) alloy that includes providing a master alloy powder comprising a metal or metal alloy and particles of a metal oxide; adding the master alloy powder to a molten diluent alloy to form an oxide-dispersion strengthened (ODS) alloy; and allowing the ODS to solidify. The molten diluent alloy includes a molten metal or metal alloy, and a wetting-enhancing metal is added to the molten diluent alloy either prior to, during, or after adding of the master alloy to the molten diluent alloy. The wetting-enhancing alloy reduces an interfacial energy and vdW attraction between the particles of the metal oxide and the molten alloy diluent to achieve a stable nanoparticulate ODS solid.
