Abstract

A creep-resistant alloy contains in percentage by weight <FORM:0990022/C6-C7/1> the Ti and Al contents being such that Ti:Al lies within the range of 0.7:1, and (Ti+Al) is between the limits defined by Mo (0.15 Cr-2.7) + (25.6-0.9 Cr) and Mo (0.15 Cr-2.7) + (23.5-0.9 Cr), the Ti and Al contents being furthermore so controlled that Mo+2Al+4Ti is not less than 22. The molten alloy may be refined by holding under high vacuum for at least 5 minutes; exemplified is treatment for 90 minutes at 1500 DEG C. under a pressure not exceeding 200 microns. A heat treatment sequence referred to consists of 1 1/2 hours at 1200 DEG C. air cooling, 6 hours at 1050 DEG C. and again air cooling. The alloy may be used for turbine parts.
