  • FABRICATION OF HIGH-ENTROPY ALLOY WIRE AND MULTI-PRINCIPAL ELEMENT ALLOY WIRE
    Publication number: 20220126402
    Abstract: In various embodiments, metallic wires are fabricated by combining one or more powders of substantially spherical metal particles with one or more powders of non-spherical particles within one or more optional metallic tubes. The metal elements within the powders (and the one or more tubes, if present) collectively define a high entropy alloy of five or more metallic elements or a multi-principal element alloy of four or more metallic elements.
    Type: Application

  • Boron addition for making potassium-doped tungsten
    Patent number: 6478845
    Abstract: A boron addition for making potassium-doped tungsten powder is described herein. Boron is added to a potassium-doped starting material, preferably in the form of boric acid, and then the mixture is reduced to form a potassium-doped tungsten powder. The boron addition results in increased potassium incorporation in the potassium-doped tungsten powder and also effects an increase in potassium retention in sintered compacts of the potassium-doped tungsten powder.
