A crystallographic defect is an interruption of the regular patterns of arrangement of atoms or molecules in crystalline solids. The positions and orientations of particles, which are repeating at fixed distances determined by the unit cell parameters in crystals, exhibit a periodic crystal structure, but this is usually imperfect. Several types of defects are often characterized: point defe… WebJun 10, 2024 · While the morphological texture is characterised by a mainly columnar shape of the grains, the crystallographic texture is marked by a preferred grain orientation in …

Weballoy, Cu and Au occupy the same crystallographic sites of the FCC structure. To calcu-late the Bragg scattering from such an alloy, one should use the average atomic scattering factor (fave(0) = 45:7). However, locally, the scattering factor varies between that of Cu (fCu(0) = 29) and Au (fAu(0) = 79). This local fluctuation, as we shall see ...
