| Abstract: | In this paper, the effect 0f pre-aging treatment on the structure of single crystal su-' perall0y CMSX-3 has been studied by optical microscope, SEM and TEM. The high temperaturefatigue behavior under different treatmept c0nditi0ns has also been investigated. The results showthat the appropriate pre-aging treatment can effectively relieve the un-unif0rmity of structure andcompositi0n, obtain suitable morphology and size 0f Y' precipitati0n and pr0l0ng the high tempera-ture fatigue lifetime of the all0y |
