Abstract
An article of a base metal alloyed with an alloying element is prepared by mixing a chemically reducible nonmetallic base-metal precursor compound of a base metal and a chemically reducible nonmetallic alloying-element precursor compound of an alloying element to form a compound mixture. The base metal is nickel, cobalt, iron, iron-nickel, or iron-nickel-cobalt. One or more of the alloying elements are thermophysically melt incompatible with the base metal. The method further includes chemically reducing the compound mixture to a metallic superalloy, without melting the metallic superalloy, and thereafter consolidating the metallic superalloy to produce a consolidated metallic article, without melting the metallic superalloy and without melting the consolidated metallic article.
