| 英文摘要 | The microstructure of hot-corrosion resistant single crystal superalloy with different Ta and Co contents and the microstructure stability during long-term aging at 1000 degrees C. was investigated. The results show that in the single crystal superalloy of the experiment, the dissolution temperature of gamma' phase increases with the increase in Ta content, the size of gamma' phase first increases and then decreases after complete heat treatment. The dissolution temperature of gamma' phase decreases and the size of gamma' phase and the content of gamma' phase reduce with the increase in Co content. During the long-term aging process at 1000 degrees C, the coarsening rate of gamma' phase first decreases and then increases with the increase in Ta content, while the coarsening rate of gamma' phase decreases with the increase in Co content. The mismatch degree of gamma/gamma' phase and the diffusion of elements in matrix are the main factors affecting the coarsening rate of gamma' phase in the four alloys. In addition, Ta increases the content of gamma' phase, promotes the distribution of Re, W, Mo and Cr toward gamma matrix, and promotes the precipitation of tcp phase, while Co reduces the distribution of Re, W, Mo and Cr in gamma matrix, reduces the supersaturation of matrix and inhibits the precipitation of tcp phase. |
