ABSTRACT:
A metallic article made of metallic constituent elements is fabricated from a mixture of nonmetallic precursor compounds of the metallic constituent elements. The mixture of nonmetallic precursor compounds contains more of a base-metal element, such as nickel, cobalt, iron, iron-nickel, and iron-nickel-cobalt than any other metallic element. The mixture of nonmetallic precursor compounds is chemically reduced to produce a metallic superalloy material, without melting the metallic superalloy material. The metallic superalloy material is consolidated to produce a consolidated metallic article, without melting the metallic superalloy material and without melting the consolidated metallic article.
