ABSTRACT:
An oxide-dispersion-strengthened sintered alloy improved in oxidation resistance and compressive strength for use at high temperatures of at least 1350.degree. C. The alloy includes a matrix of a metal consisting substantially or predominantly of Cr, and 0.2 to 2.0% by weight of Y.sub.2 O.sub.3 uniformly dispersed in the matrix. The Y.sub.2 O.sub.3 as uniformly dispersed is up to 0.1 .mu.m in mean particle size.
