Abstract
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.
