Abstract
A method for preparing an article of a base metal alloyed with an alloying element includes the steps of preparing a compound mixture by the steps of providing a chemically reducible nonmetallic base-metal precursor compound of a base metal, providing a chemically reducible nonmetallic alloying-element precursor compound of an alloying element, and thereafter mixing the base-metal precursor compound and the alloying-element precursor compound to form a compound mixture. The compound mixture is thereafter reduced to a metallic alloy, without melting the metallic alloy. The step of preparing or the step of chemically reducing includes the step of adding an other additive constituent. The metallic alloy is thereafter consolidated to produce a consolidated metallic article, without melting the metallic alloy and without melting the consolidated metallic article.
