Abstract
A nickel base superalloy for use at temperatures of 2000.degree. F (1095.degree. C) to 2200.degree. F (1205.degree. C) as a stator vane material in advanced gas turbine engines. The alloy has a nominal composition in weight percent of 16 tungsten, 7 aluminum, 1 molybdenum, 2 columbium, 0.3 zirconium, 0.2 carbon and the balance nickel.
Claims5
A nickel-base alloy adapted for use at elevated temperatures between about 2000.degree. F. and about 2200.degree. F. consisting essentially of from 15-17 percent tungsten, from 6.8-7.2 percent aluminum, from 0.8-1.8 percent molybdenum, from 1.8-2.2 percent columbium, from 0.2-0.4 percent zirconium, from 0.15-0.20 percent carbon, and the balance nickel.
A nickel base alloy about 16 percent tungsten, about 7 percent aluminum, about 2 percent columbium, about 0.2 percent carbon, about 1 percent molybdenum, and about 0.3 percent zirconium.
