摘要	In order to reveal the temperature dependence of anisotropic stress rupture behavior of SRR99 single crystal superalloys under conditions of temperature ranging from 650 to 1 040 degrees C and typical stresses, fracture morphologies and microstructure evolution were investigated by SEM and TEM. From the Larson-Miller curves, it is found that single crystal with [001] orientation has the optimum stress rupture property in comparison with [011] and [111] orientations at lower and intermediate temperature. With increasing temperature to 1 040 degrees C, stress rupture properties of single crystals with three principal orientations tend to be equivalent. Based on the fracture surface and microstructural observations, superior stress rupture behavior of single crystal with [001] orientation was rationalized and the effect of misorientation of single crystal on stress rupture property was also discussed.
