Abstract

Niobium-base alloys containing a dispersion of a hafnium-bearing carbide, such as those disclosed in Specification 1, 011, 781 are given enhanced mechanical properties by heat treatment firstly at a temperature exceeding 1550 DEG C., and secondly at a temperature in the range 1000 DEG -1350 DEG C. The first step may be effected by melting the alloy or by its deposition by fusion welding. Duration of the treatments is not critical but preferably should not exceed 2 hours for a solid-state first stage treatment; in the second stage time is dependent on temperature and should not exceed 5 hours at the upper end of the range.
