Texture Analysis of Polycrystalline Materials - Application Note

Polycrystalline materials are constituted by a large amount of crystallites which, in the ideal case of powders, have random orientation with respect to a reference frame. Quite often, there is a departure from the ideal behavior, due to the presence of a preferred orientation of crystallites or texture: this results into an X-Ray diffraction pattern characterized by modified relative intensities with respect to the reference powder one. Thus, in order to perform structural and quantitative phase analysis of polycrystalline samples, texture modelling is required.
