摘要	Microstructural degradation after thermal exposure of a 5% Re-containing single crystal (SX) superalloys has been studied. The alloy was subjected to thermal exposure at temperature of 1100 degrees C for periods of 100, 500, and 1000 h. The microstructure of the alloy was degraded after long-term thermal exposure, mainly in gamma' coarsening, the precipitation topologically close packed (TCP) phases. Moreover, the stress-rupture properties of the samples before and after long-term thermal exposures were characterized. The results showed that the gamma' coarsening and TCP formation after exposed for 500 h, which led to a damaged of the stress-rupture life time. Besides, the growth of pores during exposure also influences the stress-rupture life.
