Abstract
A heat-resistant material having excellent high-temperature strength and high oxidation resistance at temperatures exceeding 1300.degree. C. The material is a heat-resistant Cr-Fe alloy including at least 60% of Cr and at least 5% of Fe, and having a mean grain size of at least 50 .mu.m and having a melting point of at least 1600 .degree. C., or a composite material composed of the said heat-resistant alloy serving as a metal matrix and a ceramic, and containing up to 40% by volume of a dispersed ceramic phase in the metal matrix.
