Abstract:
Ni—Cr—Co—Mo—Al based alloys are disclosed which contain 15 to 20 wt. % chromium, 9.5 to 20 wt. % cobalt, 7.25 to 10 wt. % molybdenum, 2.72 to 3.89 wt. % aluminum, certain minor elemental additions, along with typical impurities, a tolerance for up to 10.5 wt. % iron, and a balance of nickel. These alloys are readily fabricable, have high creep strength, and excellent oxidation resistance up to as high as 2100° F. (1149° C.). This combination of properties is useful for a variety of gas turbine engine components, including, for example, combustors.

Claim (Index 23):
A nickel-chromium-cobalt-molybdenum-aluminum based alloy that when in annealed sheet form has an average metal affected value of not more than 3 mils/side when subjected to oxidation testing in flowing air at 2100\u00b0 F. for 1008 hours, has a creep-rupture life of at least 325 hours when tested at 1800\u00b0 F. under a load of 2.5 ksi, has ductility of greater than 10% when tested using a room temperature tensile test following a thermal exposure at 1400\u00b0 F. for 100 hours, and has a modified CHRT test ductility greater than 7% when tested at 1450\u00b0 F., the alloy having a composition comprised in weight percent of: 15.3 to 19.9 chromium 9.7 to 20.0 cobalt 7.5 to 10.0 molybdenum 2.72 to 3.78 aluminum up to 4.5 iron 0.02 to 0.49 titanium 0.085 to 0.120 carbon 0.002 to 0.005 boron up to 1.0 niobium up to 1.94 tungsten 0.13 to 0.49 silicon up to 1.0 tantalum up to 0.48 hafnium up to 0.5 manganese up to 0.02 yttrium 0.01 to 0.04 zirconium with a balance of nickel and impurities, the alloy further satisfying the following compositional relationship defined with elemental quantities being in terms of weight percent:\n Al+0.56Ti+0.29Nb+0.15Ta\u22643.89.
