| 中文摘要 | A six-dimensional (6D) crystal-structure model has been constructed for the icosahedral quasicrystal i-(Al-Mn-Si). The positions of the 6D hypercubic atoms are determined from the atomic coordinates of alpha-(Al-Mn-Si). There are 38 atoms in the 6D unit cell, and the number of inequivalent atoms is 4: One Mn atom is located at the origin, one (Al,Si) atom at the body center, and six (Al,Si) atoms at edge centers; the remaining 30 (Al,Si) atoms are distributed along the 15 face diagonals, and every two atoms divide a diagonal in the ratios tau--2:tau--3:tau--2, Where tau = (1 + square-root 5)/2. The 6D space group is Pm35BAR. The projection of the 6D crystal onto the physical space with a rational (1/1) strip gives alpha-(Al-Mn-Si), and the projection with an irrational (tau/1) strip gives i-(Al-Mn-Si). The idealized projection windows for obtaining i-(Al-Mn-Si) are polyhedra given by considering the similarity between the local atomic arrangements of i-(Al-Mn-Si) and those of alpha-(Al-Mn-Si) and also between the local environments of three-dimensional Penrose tiling and those of a rhombic tiling for the body-centered-cubic structure. The chemical composition and mass density of the obtained i-(Al-Mn-Si) quasicrystals have been calculated with the idealized projection windows. Electron diffraction patterns simulated with the approximate projection windows have been compared with the experimental patterns of i-(Al-Mn). |
