An article has a metallic matrix made of its constituent elements with a dispersoid
distributed therein. The article is prepared by furnishing at least one nonmetallic
matrix precursor compound. All of the nonmetallic matrix precursor compounds collectively
include the constituent elements of the metallic matrix in their respective constituent-element
proportions. A mixture of an initial metallic material and the dispersoid is produced.
The matrix precursor compounds are chemically reduced to produce the initial metallic
material, without melting the initial metallic material, and the dispersoid is
distributed in the initial metallic material. The mixture of the initial metallic
material and the dispersoid is consolidated to produce a consolidated article having
the dispersoid distributed in the metallic matrix comprising the initial metallic
material. The initial metallic material, the dispersoid, and the consolidated article
are not melted during the consolidation.
