Abstract

An alloy containing in percentage by weight <TABS:1124044/C6-C7/1> is heat-treated at 982 DEG -1238 DEG C. for about 4 hours, followed by heating at 1204 DEG -1238 DEG C. for several hours, and a final heating at 816 DEG -899 DEG C. for 1 - 3 days, the alloy being cooled after each of the three heating operations. The treatment is particularly applicable to turbine blades and vanes, especially those which have been coated by the process of British Patent No. 966589, the heating step of that process forming the first heating step of the present invention.
