Abstract
A method for preparing a metallic article made of metallic constituent elements includes furnishing a mixture of nonmetallic precursor compounds of the metallic constituent elements. The method further includes chemically reducing the mixture of nonmetallic precursor compounds to produce an initial metallic material, without melting the initial metallic material, and consolidating the initial metallic material to produce a consolidated metallic article, without melting the initial metallic material and without melting the consolidated metallic article. A net macroscopic composition of the consolidated metallic article varies spatially according to a pre-selected pattern
