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 three-dimensional parts are fabricated by providing a powder bed containing particles each comprising a mixture and/or alloy of constituent elemental metals, forming a first layer of the part by (i) dispersing a binder into the powder bed, and (ii) curing the binder, the first layer of the shaped part comprising particles bound together by cured binder, disposing a layer of the particles over the first layer of the part, forming subsequent layers of the part, and then sintering the part.

Abstract: In various embodiments, powders with engineered particle-size distributions are slip or pressure casted to produce homogeneous parts without the need for additives such as flocculating or deflocculating agents.

Abstract: A composite is produced by the steps of (a) blending a first mixture of metallic powders; (b) compacting the blended first mixture of metallic powders to a plurality of discretely shaped articles; (c) blending a second mixture of metallic powders; (d) mixing the plurality of discretely shaped articles with the blended second mixture of metallic powders to form a precursor blend; (e) compacting the precursor blend; and (f) sintering the precursor blend. The composite has a metallic matrix with embedded shapes dispersed throughout the matrix where the embedded shapes have an incipient liquid phase sintering temperature less than an incipient liquid phase sintering temperature of the matrix.

Abstract: A single phase metal alloy usually for forming a shaped charge liner for a penetrating jet or explosively formed penetrator forming warhead consists essentially of from a trace to 90%, by weight, of cobalt, from 10% to 50% by weight, of tungsten, and the balance nickel and inevitable impurities. One preferred composition is, by weight, from 16% to 22%, cobalt, from 35% to 40% tungsten and the balance is nickel and inevitable impurities. The alloy is worked and recrystallized and then formed into a desired product. In addition to a shaped charge liner, other useful products include a fragmentation warhead, a warhead casing, ammunition, radiation shielding and weighting.
