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.
