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 10):
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 to 20 chromium 9.5 to 20 cobalt 7.25 to 10 molybdenum 2.72 to 3.89 aluminum up to 5 iron 0.02 to 0.75 titanium present up to 0.15 carbon present up to 0.6 silicon up to 0.015 boron up to 1 niobium up to 1.5 tantalum up to 1 hafnium up to 2 tungsten up to 1 manganese up to 0.06 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\u22643.9.
