    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an oxide-dispersed alloy in an ideal state where metal oxide is more finely dispersed. SOLUTION: The method for producing an oxide-dispersed alloy in which dispersion grains composed of the oxide of one or more kinds of additional metals are dispersed into a base phase metal(s) comprises: a stage (a) where alloy powder or alloy wire rod composed of a base phase metal(s) and an additional metal(s) is produced; a stage (b) where the alloy powder or alloy wire rod is introduced into a high energy ball mill together with water, and stirring is performed, thus the additional metal(s) in the alloy powder is oxidized with the water, so as to form dispersion grains; and a stage (c) where the alloy powder or alloy wire rod after the oxidation is compacted. The invention is particularly useful for producing an oxide-dispersed alloy in which the oxide formation free energy of the base phase metal(s) is higher than the standard formation free energy of water, and the oxide formation free energy of the additional metal(s) is lower than the standard formation free energy of water.

    Abstract: PROBLEM TO BE SOLVED: To provide a heat-resistant alloy which has a similar composition to Inconel (R)713C, and can be formed into fine powder to be metal-injection-molded with a spray method.
    SOLUTION: This heat-resistant alloy comprises, by mass%, 0.08-0.20% C, 0-0.25% Mn, 0-0.015% S, 0.2-1.0% Si, 12.0-14.0% Cr, 3.80-5.20% Mo, 0-0.1% Ti, 5.50-6.50% Al, 2.58-4.74% Nb, 0-2.5% Fe, 0.05-0.15% Zr, 0-0.015% B, 0-1.00% Co, and the balance Ni with unavoidable impurities. Because the alloy has the composition which substitutes Nb for Ti in Inconel 713C and does not include Ti, it does not cause clogging during teeming in process of producing the fine powder with the spray method.
