Abstract

An alloy containing in percentage by weight: <TABS:1014438/C6-C7/1> is solution treated at 1600-2100 DEG C. for 5 minutes to 9 hours, and is subsequently treated at 1000-1500 DEG C., for 1/2 hour to 40 hours, the conditions of the second treatment being such that the metal recrystallizes. Cooling at a rate such as 300 DEG C./min. from the solution treatment temperature down to 1200 DEG C. is preferable. An intermediate working step can be carried out between the two stages of heat treatment but deformation by cold work should not exceed 40%. The alloys may be prepared by arc melting or by powder metallurgical methods.
