Abstract (en)
[origin: GB2417729A] A nickel-chromium-cobalt based alloy has a composition comprising (by weight): 17-22 % chromium, 8-15 % cobalt, 4.0-9.5 % molybdenum, 1.28-1.65 % aluminium, 1.50-2.30% titanium, 0.01-0.2 % carbon, up to 7.0 % tungsten, up to 0.80 % niobium, up to 0.015 % boron, up to 3 % iron, up to 1.5 tantalum, up to 1.5 % manganese, up to 0.5 % silicon, up to 0.5 % copper, up to 0.5 % each of magnesium, calcium, hafnium, zirconium, yttrium, cerium and lanthanum, with the balance being nickel and impurities. The sum of A1 + 0.56Ti + 0.29Nb lies between 2.2-2.9 and the sum of Mo + 0.52W lies between 6.5-9.5. The alloy may be used in wrought, cast, spray-formed of powder form and used to make components for gas turbine engines.
