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.
