摘要：
Low cycle fatigue and creep tests were performed on superalloy single crystals CMSX-4 to determine the effect of orientation and temperature on the stress-strain response and on the lifetime. The resistance against fatigue at 700 degrees C decreases in the order of [001], [011], [111] orientations. For creep the ranking depends both on the temperature and on the applied stress. These results are correlated with the microstructural changes taking place during loading.
