| 摘要 | The investigation of phase structures and defects in material at the atomic scale is now deep-going into their physical essence, such as structural stability of the phases, atomistic relax at the interfaces, and so on. In this paper, we choose TiAl-based alloys as an example, because they are primary candidates for high-temperature structural materials for their low density, high strength and good anti-oxidation property. Based on HREM observation, nano-beam EELS and EDS analysis and ab initio pseudopotential calculation for the cohesive energy of compound, the Ti2Al phase has been identified. Using HREM observation and molecular dynamics calculation, the atomic structures of symmetrical and asymmetrical tilting grain boundaries have been characterized. |
