Crystallography of quasiperiodic crystals
WebMar 6, 2024 · The determination of orientation relationships in dual or multi-phase materials is very important in the field of interface engineering for the design of materials with tailored properties. In this work, a code is developed for the automated and statistical analysis of the orientation relationship of electron backscatter diffraction data. The code is applied to the … WebThe development of the concept of quasicrystals has challenged many widely held assumptions of crystallography and solid state physics. It had been generally assumed that pentagonal symmetry is impossible in solids, that Bragg diffraction peaks imply periodic translational order, that all pure solids are either crystalline or glassy, and that the …
