| 摘要 | The effects of microstructure on the creep behavior in a new developed Ni-Co base superalloy were investigated and two microstructures were obtained by different heat treatments. The results show that the air cooling microstructure, consisting of large spherical gamma' and small spherical gamma', resulted in a slow creep rate and small creep strain. While the slow cooling microstructure, consisting of large flowery gamma' and small spherical gamma', resulted in a fast creep rate and large creep strain. The gamma channel and gamma' morphology are two main factors for these differences, the large gamma channel and flowery gamma' in the slow cooling microstructure causing the dislocations slip easily in the gamma matrix and cut into the gamma' precipitates with low stress. |
