Abstract
Turbocharger turbine wheels including nickel-based alloys are disclosed herein. In one exemplary embodiment, a turbocharger turbine wheel includes as, at least part of its constituency, a nickel-based alloy that includes, on a weight basis of the overall alloy: about 10.5% to about 11.5% cobalt, about 9.0% to about 10.0% chromium, about 5.75% to about 6.25% aluminum, about 2.8% to about 3.3% tantalum, about 4.0% to about 4.5% molybdenum, about 2.2% to about 2.4% titanium, about 0.13% to about 0.15% carbon, about 0.03 to about 0.09% zirconium, and a majority of nickel. The nickel-based alloy excludes tungsten except in unavoidable trace amounts. The turbocharger turbine wheel may be configured for operating at about 980° C. to about 1020° C.
