Abstract (en)
An article of iron base metal base metal alloyed with an alloying element is prepared by mixing (44) a chemically reducible nonmetallic base-metal precursor compound (40) of the iron base metal and a chemically reducible nonmetallic alloying-element precursor compound (42) of an alloying element to form a compound mixture. The alloying element is preferably thermophysically melt incompatible with the iron base metal. The method further includes chemically reducing (48) the compound mixture to a metallic alloy, without melting the metallic alloy, and thereafter consolidating (50) the metallic alloy to produce a martensitic-composition consolidated metallic article, without melting the metallic alloy and without melting the consolidated metallic article.
