A method of making a superfine alloy comprises: incorporating a grain growth inhibitor polymeric precursor into a composition for synthesis of a superfine material; synthesizing the superfine material from the composition comprising the incorporated precursor; incorporating an alloy additive into the composition for synthesis of the superfine material before synthesizing the superfine material, or alternatively, into the as-synthesized superfine material to produce a superfine alloy-grain growth inhibitor polymeric precursor composite; and treating the superfine alloy-grain growth inhibitor polymeric precursor composite to convert the grain growth inhibitor polymeric precursor to a grain growth inhibitor.

Methods of making superfine alloys

A superfine material made by incorporation of an inorganic polymer precursor of a grain growth inhibitor into intermediates useful for the production of superfine materials. The precursor/nanostructured material composite is optionally heat treated at a temperature below the grain growth temperature of the superfine material in order to more effectively disperse the precursor. The composites are then heat treated at a temperature effective to decompose the precursor and to form superfine materials having grain growth inhibitors uniformly distributed at the grain boundaries. Synthesis of the inorganic polymer solution comprises forming an inorganic polymer from a solution of metal salts, filtering the polymer, and drying. Alloying additives as well as grain growth inhibitors may be incorporated into the superfine materials.
