Method for preparing a metallic article having an other additive constituent, without any melting

A method for preparing an article of a base metal alloyed with an alloying element, comprising the steps of

• preparing a precursor compound by the step 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;
• thereafter chemically reducing the precursor compound to form a metallic alloy, without melting the metallic alloy,
• consolidating the metallic alloy to produce a consolidated metallic article, without melting the metallic alloy and without melting the consolidated metallic article,
• where in an other additive constituent is added during the step of chemically reducing and wherein the other additive constituent is an element, mixture of elements, or compound that makes up a portion of the final alloy content of the metallic alloy that is not itself reduced during the step of chemically reducing the precursor compound.

• where in the step of chemically reducing includes a step selected from the group consisting of
• mixing solid particles comprising the other additive constituent with the metallic alloy,
• depositing from a gaseous phase the other additive constituent on a surface of the metallic alloy, and
• depositing from a liquid phase the other additive constituent on a surface of the metallic alloy.
