The achievement of high efficiency in large land-based stationary gas turbines for electric power generation requires increased gas temperatures. Gas temperatures higher than 1300 C can only be handled using air-cooled structures to keep the metal temperature below 1000 C. Only columnar grained (directionally solidified, DS) or single crystal (SC) superalloys have the required creep strength and thermo-mechanical fatigue resistance. The superalloy IN 792 DS shows anisotropic properties especially with respect to Young's modulus and creep rates. For different thermal cycles the temperature distribution in the cross-section of the blade was calculated with finite element methods. Based on the calculated temperature distribution, the stress an...
