Abstract

Improvement of Nb-alloys, which are known as heat-resistant alloys, by giving anti-oxidation property thereto and increasing the high temperature strength thereof. In addition to a determined amount of Al, one of (1) suitable amounts of Ti, Cr and V, and (2) suitable amounts of Cr and Co, are added to Nb-matrix, and a high melting temperature metal oxide such as Y.sub.2 O.sub.3 or Al.sub.2 O.sub.3 is dispersed in the matrix. Preferable method of preparing the alloys is combination of mechanical alloying and subsequent hot processing.
