Abstract

A method of forming a nickel-chromium alloy containing aluminium with or without titanium with the solubility temperature of the g 1 phase higher than that of the carbide phase comprises solution heating the alloy above the solubility temperature of the g 1 phase, cooling to a temperature between the g 1 phase solubility temperature and the carbide phase solubility temperature, keeping it at this temperature until a precipitate of the g 1 phase has formed at the grain boundaries and then hot working it. The alloys which may be treated according to the present invention comprise <TABS:0951075/C3/1> Si, Mu and Fe should be kept as low as possible, Si and Mu not exceeding 0.5% each and Fe not exceeding 1%. In examples, rods of alloys within the above ranges were solution heated at 1190 DEG C. for 1.5 hours, cooled to 1000 DEG C. at 1 or 2 DEG C. per minute, then optionally further cooled to room temperature and then reheated to 1120 DEG C. at which temperature they were hot-worked.
