| 英文摘要 | The influence of solution temperature on the microstructure evolution and creep behavior of a new Ni-Co base superalloy for turbine discs, including the grain morphology, grain boundary character distribution (GBCD), and grain boundary (GB) carbide morphology, was investigated using scanning electron microscopy (SEM), electron backscatter diffraction (EBSD), and transmission electron microscopy (TEM). The results showed that the creep fracture life first increased and then decreased with increasing solution temperature. The alloy solution treated at 1140 degrees C exhibited the best creep properties, with a creep life of 209 h. The enhanced creep performance of this alloy can be explained as follows: the volume fraction of GB carbides increased with increasing solution temperature, the diffuse fine granular carbides relieved stress concentration and strengthened GBs, the coarse primary gamma ' phases rapidly dissolved, and the volume fraction of the fine and dispersed secondary and tertiary gamma MODIFIER LETTER PRIME phases significantly increased. The narrower channels in the gamma matrix increased the resistance to dislocation motion. The coherent sigma 3 twin boundaries (TBs) with low interface energy hindered the dislocations and stacking faults intersecting the TBs on different slip planes. The relative frequency of sigma 3 TBs increased to 53.6% when the solution temperature was increased to 1140 degrees C. The high proportion of sigma 3 TBs played a key role in improving the creep resistance of the alloy. |
