The paper deals with the properties and structures of two superalloys differing in the gamma/gamma’ morphology. The creep resistance of the 001, 011 and 111 oriented single crystals of superalloys CMSX-4 and CM186LC was compared on the basis of creep rupture curves, creep deformation curves and accompanying development of microstructures in the temperature interval 750 to 950 °C. Further, the effect of notches on creep behaviour and the origin of creep cracks were examined.
