A nickel-chromium-iron alloy intended principally for automotive turbocharger applications, the alloy being characterized by good stress - rupture strength, ductility, tensile strength, etc. and containing, generally speaking, 10-15% Cr, 18-30% Fe, 3-4.25% Ti, 2.25-3.5% Al, Ti+Al from 6 to 7.25%, ratio of Ti to Al of at least 0.9 and up to 1.6, 4-6% Mo, 0.01-0.2% B, 0.03-0.3% C, balance essentially nickel.

Nickel-chromium-iron alloy

An oxide dispersion-strengthened, nickel-base alloy containing special amounts of chromium, aluminum, tungsten, molybdenum and yttria has a combination of strength properties over a range of temperatures, together with substantial corrosion resistance.

Dispersion-strengthened nickel-base alloy

Nickel-base alloy containing chromium, aluminum, titanium, molybdenum, cobalt and tungsten has combination of strength and ductility at elevated temperatures, particularly including stress-rupture strength at 980.degree. C. and ductility at 760.degree. C., along with resistance against oxidation and to hot corrosion by combustion products from jet engine fuels. The alloy is especially useful in production of gas turbine rotor blade castings.

Nickel-based alloy

Nickel-base alloy containing chromium, aluminum, titanium and molybdenum, and desirably including cobalt and metal from group tungsten and tantalum, has combination of strength and ductility at elevated temperatures, particularly including stress-rupture strength at 1800.degree. F. and ductility at 1400.degree. F., along with resistance against oxidation and to hot corrosion by combustion products from jet propulsion fuels. Alloy is especially useful in production of gas turbine rotor blade castings.
