Application of the Dynamical Theory of X-ray Diffraction to Copperzinc Mahmud Readul

X-ray diffraction technique have been using for a long time to understand the characteristics of various materials around the world. So it is important to understand the kinematics and dynamical theory and their applications in different cases. So dynamical theory of x-ray diffraction for both absorption and without absorption is developed and applied to thin, thick and intermediate thick CuZn alloy to obtain the diffraction patterns for both Bragg's and Laue's cases. The famous asymmetric curve is found when absorption is considered; the diffraction curve is symmetrical without absorption. It is found that the intensity increases but FWHM decreases for higher indices. Order-disorder transformation of CuZn binary alloy is also noticed for various temperatures. The atomic scattering factors of different elements are calculated to see the temperature effect. The temperature dependence of reflection lines are computed using Debye and Einstein approximation. Interestingly intensity of reflection lines decreases with the increase of temperature and indices for both cases. This book will be helpful for the student and researchers who want to understand and work on x-ray diffraction.
