METHOD FOR PREPARING METALLIC ARTICLE HAVING ANOTHER ADDITIVE CONSTITUENT, WITHOUT ANY MELTING

摘要

PROBLEM TO BE SOLVED: To prepare a metallic-alloy article having another additive constituent, without melting of the metallic alloy.SOLUTION: A method for preparing an article (20) 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 chemically reducing includes the step of adding another additive constituent. The metallic alloy is thereafter consolidated to produce a consolidated metallic article (20), without melting the metallic alloy and without melting the consolidated metallic article (20).
