| Abstract | Microstructural characteristics of an experimental Ni-based superalloy with boron addition subjected to a long-term ageing treatment were systematically investigated by various kinds of transmission electron microscopy technique. Based on detailed electron diffraction analyses, we found that there are many nanosized M5B3 precipitates in our long-term ageing alloys, which keeps a good orientation relationship with the gamma/gamma' matrix. Furthermore, the precipitation characteristics of M5B3 phase were clarified. It is found that the M5B3-type boride prefers to precipitate at the gamma/gamma' interfaces and low-angle grain boundaries. These interfacial nanosized precipitates can play the role of pinning effect and are expected to be advantageous for postponing the gamma' rafting and low-angle grain boundary migration to some extent at high temperature. |
