Patent ID: 6921510

Claim:
A method of preparing an article comprising a metallic matrix having its constituent elements and a dispersoid distributed therein, comprising the steps of furnishing at least one nonmetallic matrix precursor compound, all of the nonmetallic matrix precursor compounds collectively including the constituent elements of the metallic matrix in their respective constituent-element proportions; thereafter producing a mixture of an initial metallic material and the dispersoid, the step of producing including the step of chemically reducing the matrix precursor compounds to produce the initial metallic material, without melting the initial metallic material, wherein the initial metallic material is selected from the group consisting of a nickel-base material, a cobalt-base material, a titanium-base material, a magnesium-base material, and an aluminum-base material; and consolidating the mixture of the initial metallic material and the dispersoid to produce a consolidated article having the dispersoid distributed in the metallic matrix comprising the initial metallic material, without melting the initial metallic material, without melting the dispersoid, and without melting the consolidated article.
