<P>PROBLEM TO BE SOLVED: To provide a sintered alloy which further improves heat resistance, oxidation resistance, and corrosion resistance, and a method for manufacturing the sintered alloy. <P>SOLUTION: The Ni-based sintered alloy has a composition consisting of 15-23 mass% Cr, 0.5-3.0 mass% compound containing at least one of O selected from rare earth elements, and the balance being Ni and inevitable impurities. The Ni-based sintered alloy has a metallic structure in which particles of the compound with a maximum particle diameter of 10 μm or less are dispersed in a Ni-Cr alloy matrix with a maximum crystal particle diameter of 50 μm or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
