For environmental reasons an increase of the efficiencies of power stations is needed and further improvements of materials are essential. Today combined gas and steam turbine power stations obtain overall efficiencies of 58 %. Temperatures of approximately 1230 °C in gas turbines exceed the load limits of the commonly used materials. For efficiency increase turbine inlet temperatures must be increased up to 1350 °C (ISO) in the gas turbine.
