| 1. A method for producing a solid metallic alloy composition, comprising:
(a) reacting a gaseous metal halide with a reducing agent in a manner effective to form a nonsolid reaction product, wherein
the gaseous metal halide has a formula
MXi,
wherein M is a metal selected from a transition metal of the periodic table, aluminum, silicon, boron, and combinations thereof,
X is a halogen,
i is greater than 0,
the reducing agent is a gaseous reducing agent selected from hydrogen, a compound that releases hydrogen, and combinations
thereof, and
the reacting is carried out in a presence of an alloying agent or a precursor thereof; and
(b) solidifying the nonsolid reaction product, thereby forming a metallic alloy composition comprising M that is substantially
free from halides, wherein the nonsolid reaction product is deposited on a surface of a substrate during step (b).
