| 摘 要： | 根据热力学原理,考察了Fe-Al系金属间化合物与ZrO2陶瓷基体的化学相容性。结果表明,当Fe-Al金属间化合物中Al<42at％时,Fe-Al金属间化合物与ZrO2基体不易发生化学反应。XRD、SEM及HREM分析验证了此结论。HREM观察表明Fe3Al与基体3Y-TZP之间界面干净,无反应层和过渡层的存在,Fe3Al与ZrO2界面两侧的原子排列不是一一对应的,只是部分互相匹配,形成半共格关系。界面上品面间错配度δ=30％,界面上存在着错配位错。 |

| Abstract: | The chemically compatibility of iron aluminide with zirconia matrix was analyzed by thermodynamic theory. The results show that the chemical interaction between iron aluminide intermetallic and zirconia matrix will not take place when Al<42at%, and this result was certified by XRD,SEM and HREM. HREM image exhibits that the interface between Fe3Al and 3Y-TZP is clean, and no reaction phase exists at the interface. The atom arrangement beside interface between Fe3Al and ZrO2 is partly corresponding, existing at semicoherent state. The mismatch degree δ of spacing between planes in crystal is 30%, and the dislocation induced by mismatch exists at interface. |
| Keywords: | composite chemical compatibility thermodynamic calculation interface |
