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.

- 12. A multi-principal element alloy wire preform comprising four or more metallic elements, the wire preform comprising an assemblage of (i) one or more first metal powders each comprising one or more of the metallic elements, wherein particles of each first metal powder are substantially spherical, and (ii) one or more second metal powders each comprising one or more of the metallic elements, wherein particles of each second metal powder are non-spherical.

53. A method of fabricating a metallic wire, the method comprising:
-
combining, to form at least a portion of a preform, (i) one or more first metal powders each comprising a plurality of substantially spherical particles, and (ii) one or more second metal powders each comprising a plurality of non-spherical particles, the one or more second metal powders being mixed with the one or more first metal powders such that a composition of the preform is substantially homogeneous along a length of the preform; and reducing a diameter of the preform via one or more mechanical deformation processes, thereby forming a metallic wire, wherein (i) the metallic wire comprises a high-entropy alloy comprising five or more metallic elements or a multi-principal element alloy comprising four or more metallic elements, (ii) each first metal powder comprises at least one of the metallic elements, and (iii) each second metal powder comprises at least one of the metallic elements. - View Dependent Claims (54, 59, 62, 63, 64, 66, 67, 72)
