Abstract (en)
A nickel-based alloy composition and turbine vanes and blades including from about 8 % to about 18 % cobalt, from about 12 % to about 16 % chromium, from about 4 % to about 8 % aluminum, up to about 6 % tungsten, from about 0.5 % to about 3.5 % titanium, from about 2 % to about 6 % molybdenum, from about 0.05 % to about 0.25 % carbon, from about 0.005 % to about 0.025 % boron, from about 0.02 % to about 0.1 % zirconium, up to about 1.0% iron, up to about 2.0% rhenium, up to about 2.0% tantalum, up to about 1.0 % hafnium, balance essentially nickel and incidental impurities, wherein the sum weight percent of aluminum and titanium is from about 4.5 wt% to about 13 wt%. In addition, the ratio of the weight percentage of aluminum to titanium is greater than about 1:1, preferably greater than about 2:1.
