Patent ID: 7419528

Claim:
A method for fabricating a metallic article made of metallic constituent elements, comprising the steps of furnishing a mixture of nonmetallic precursor compounds of the metallic constituent elements; chemically reducing the mixture of nonmetallic precursor compounds to produce a metallic superalloy material, without melting the metallic superalloy material, wherein the metallic superalloy material is a nickel-base superalloy having at least about 10 percent by volume of one or more strengthening discrete phases, or a cobalt-base superalloy having at least about 1 percent by volume of one or more strengthening discrete phases, or an iron-base alloy having at least about 5 percent by volume of one or more strengthening phases, or an iron-nickel-base superalloy having at least about 10 percent by volume of one or more strengthening phases, or an iron-nickel-cobalt-base superalloy having at least about 10 percent by volume of one or more strengthening phases; and consolidating the metallic superalloy material to produce a consolidated metallic article, without melting the metallic superalloy material and without melting the consolidated metallic article.
