Abstract

A nickel-base superalloy that is useful for making single crystal castings exhibiting outstanding stress-rupture properties, creep-rupture properties, and an increased tolerance for grain defects contains, in percentages by weight, from about 4.3 % to about 5.3 % chromium, (Cr), from about 9 % to about 10 % cobalt (Co), from about 0.6 % to about 0.8 % molybdenum (Mo), from about 8.4 % to about 8.8 % tungsten (W), from about 4.3 % to about 4.8 % tantalum (Ta), from about 0.6 % to about 0.8 % titanium (Ti), from about 5.6 % to about 5.8 % aluminium (Al), from about 2,8 % to about 3.1 % rhenium (Re), from about 0.9 % to about 1.5 % hafnium (Hf), from about 0.06 % to about 0.08 % carbon (C), from about 0.012 % to about 0.020 % boron (B), from about 0.010 % zirconium (Zr), the balance being nickel and incidental impurities.
