| 英文摘要 | The atomic structures of specific types of linear defects (phason lines) and planar defects (phason planes) in the complex metallic alloy phase xi'-al-pd-mn have been determined by high-resolution electron microscopy (hrem) and theoretical hrem simulation. the results show that a representational atomic structural model for phason planes can be constructed by introducing a shift between two parts of the perfect crystalline structure using a translation vector of r = (1/2)a + (1/2 tau)c. this typical phason plane is normally parallel to the (001) plane of the xi'-al-pd-mn phase and consists of phason lines, which are arranged side-by-side with their linear direction parallel to the [010] axis. hrem simulations, based on the structural model for both edge-on and inclined types of phason lines, agree well with the experimental results. taking into account the fact that the structural difference between various curved phason planes arises from the variation in the arrangement of individual phason lines, the atomic structures of the edge-on and inclined phason lines can be used to explain the various curved phason planes frequently observed in the xi'-al-pd-mn phase. |
