Abstract
An article of aluminum base-metal alloyed with an alloying element is prepared by mixing a chemically reducible nonmetallic base-metal precursor compound of the aluminum base-metal and a chemically reducible nonmetallic alloying-element precursor compound of an alloying element to form a precursor compound mixture. The alloying element may be, but is not necessarily, thermophysically melt incompatible with the aluminum base metal. The method further includes chemically reducing the precursor compound mixture to a metallic alloy, without melting the metallic alloy, and thereafter consolidating the metallic alloy to produce a consolidated metallic article, without melting the metallic alloy and without melting the consolidated metallic article.
