Patent ID: 7537636

Claim:
A method of making a superfine alloy, the method comprising: 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 wherein the superfine material is selected from the group consisting of Cu, FeCu, FeCo, NiAl, MoC, MoSi, NiCr, TiC, Mo 2 Si, NiCr/Cr 3 C 2 , Fe/TiC, Ni/TiC, Mo/TiC, and WC/Co, the foregoing alloyed with one or more of Ti, Cr, Mo, Ni, Zr, Ce, Fe, Al, Si, V. TiC, Mn, Y, W, and a combination comprising at least one of the foregoing materials.
