Crystal mosaicity
WebFeb 26, 2024 · Mosaicity can be determined by measuring the rocking curves of a crystal. Diffraction by mosaics is usually described by the Darwin–Hamilton equations. 9 , 10 In the Darwin dynamical model, a Gaussian distribution of the crystallite orientation is assumed by using a reference direction; that is, the normal vector of the mother crystal plane. WebThe mosaicity of the crystal was anisotropic, with FWHM values of 0.0068, 0.0140 and 0.0046 degrees along the a, b and c axes, respectively. The anisotropic mosaicity …

WebCrystal mosaicity in a Ni-based superalloy which was prepared by seeded Bridgman processing in the present study. The varying contrasts of dendrites are related to small misorientations WebThe mosaicity of the crystal was anisotropic, with FWHM values of 0.0068, 0.0140 and 0.0046 degrees along the a, b and c axes, respectively. The anisotropic mosaicity analysis indicates that the crystal is most perfect in the direction that corresponds to the favored growth direction of the crystal.

A mosaic crystal is an idealized model of an imperfect crystal, imagined to consist of numerous small perfect crystals (crystallites) that are to some extent randomly misoriented. Empirically, mosaicities can be determined … See more An important application of mosaic crystals is in monochromators for x-ray and neutron radiation. The mosaicity enhances the reflected flux, and allows for some phase-space transformation. Pyrolitic graphite (PG) … See more To describe diffraction by a thick mosaic crystal, it is usually assumed that the constituent crystallites are so thin that each of them reflects at most a small fraction of the … See more
WebAug 29, 2024 · The mosaicity is a measure of crystal lattice planes that are misoriented with each other and belongs to well-known defects of good quality single crystals with high perfection. Many available investigation methods for its measurements and visualization were developed [ 14 , 15 , 16 ].
