Mechanical Loading/Synchrotron X-Ray Diffraction System for In-Situ Determination of Lattice Strains

摘要

A mechanical testing/synchrotron x-ray diffraction system was fabricated in this DURIP grant. The key elements of the system are a high frequency uniaxial loading machine, a precision diffractometer support Unit and an x-ray shutter (chopper). The system will be employed within synchrotron experimental facilities to measure lattice strains during cyclic deformation experiments as a means to understand the evolution of crystal stresses.
