Abstract (en)
The alloy of the invention provides a controlled coefficient of thermal expansion alloy that age hardens. This alloy consists essentially of, by weight percent, about 32 to 55 nickel, about 6 to 16 cobalt, about 1.2 to 7 chromium, about 0.25 to 1.5 aluminum, about 0.25 to 3 titanium, about 2 to 8 total (niobium + 1/2 tantalum), about 0.1 to 1.2 silicon and balance iron and incidental impurities with iron being about 28 to 50.
