| 英文摘要 | During long-term thermal exposure M23C6 dendritically precipitates from the supersaturated gamma matrix and then changes in shape from flower-like dendrite to irregular block to regular polyhedron. The reduction in the interfacial energy is responsible for the morphological transition, but the stable morphology of the carbide is principally determined by the anisotropy of the interfacial energy between the carbide and the gamma' in the M23C6-gamma' cell. In addition, M23C6 has a negligible influence on the tensile property of the thermally exposed alloy even though it can block the mobile dislocations and stacking faults to some extent.
