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 is chemically reduced to produce an initial metallic material, without melting the initial metallic material. The initial metallic material is consolidated to produce a consolidated metallic article, without melting the initial metallic material and without melting the consolidated metallic article.
