Polarization Effects of X-ray Monochromators Modeled Using Dynamical Scattering Theory

July 1, 2021
Author(s)
Marcus Mendenhall, David R. Black, Donald Windover, James Cline
The difference in the diffracted intensity of the sigma-and pi-polarized components of an X-ray beam in powder diffraction has generally been treated according to equations based on dipole scattering, also known as kinematic X-ray scattering. Although this

The Certification of Standard Reference Material 1979: Powder Diffraction Line Profile Standard for Crystallite Size Analysis

July 31, 2020
Author(s)
James Cline, Marcus Mendenhall, Joseph J. Ritter, David R. Black, Albert Henins, John E. Bonevich, Pamela S. Whitfield, James J. Filliben
This rather long-standing project has resulted in a National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) for the analysis of crystallite size from a consideration of powder diffraction line profile broadening. It consists

New Synchrotron X-Ray Techniques for In-Situ Deformation Studies

February 19, 2017
Author(s)
Lyle E. Levine, R Thomson, Gabrielle G. Long, David R. Black
Many types of defects contribute to local and long-range stresses and strains in materials. These include vacancies, voids, prismatic loops, interstitials, inclusions, and dislocations. In most cases, dislocations play the dominant role in minimizing long
