Abstract: In various embodiments, metallic alloy powders are utilized as feedstock, or to fabricate feedstock, utilized in additive manufacturing processes to form three-dimensional metallic parts. Such feedstock includes composite particles each comprising a mixture and/or alloy of a first constituent metal and one or more second constituent metals, where each of the particles comprises a plurality of grains each surrounded by a matrix, the grains comprising the first constituent metal, and the matrix comprising the one or more second constituent metals.

Abstract: The invention is directed at sputter targets including 50 atomic % or more molybdenum, a second metal element of niobium or vanadium, and a third metal element selected from the group consisting of titanium, chromium, niobium, vanadium, and tantalum, wherein the third metal element is different from the second metal element, and deposited films prepared by the sputter targets. In a preferred aspect of the invention, the sputter target includes a phase that is rich in molybdenum, a phase that is rich in the second metal element, and a phase that is rich in the third metal element.

Abstract: In various embodiments, eroded sputtering targets are partially refurbished by spray-depositing particles of target material to at least partially fill certain regions (e.g., regions of deepest erosion) without spray-deposition within other eroded regions (e.g., regions of less erosion). The partially refurbished sputtering targets may be sputtered after the partial refurbishment without substantive changes in sputtering properties (e.g., sputtering rate) and/or properties of the sputtered films.
