Abstract
A heat resistant super alloy suffices the following conditions: carbon 0.01-0.2 percent in weight chromium 8-10 percent in weight aluminum 4-6 percent in weight titanium 2-4 percent in weight molybdenum 1.5-2.8 percent in weight tungsten 10-13.5 percent in weight niobium 1.5-2.5 percent in weight boron 0 < B ≦ 0.04 percent in weight zircon 0 < Zr ≦ 0.15 percent in weight the contents of hafnium and lanthanum together amounts to 0 < Hf + La ≦ 1.5 percent in weight, optionally traces of tantalum, the remainder being nickel. Such an alloy is preferably used for turbine wheels and particularly for turbochargers.
