TL;DR: This work determines the location and identity of every atom at a grain boundary and finds that different grains stitch together predominantly through pentagon–heptagon pairs, and reveals an unexpectedly small and intricate patchwork of grains connected by tilt boundaries.

TL;DR: Two techniques for time-resolved x-ray diffraction from bulk polycrystalline materials during dynamic loading are developed and sample data is presented demonstrating the ability of these techniques to characterize elastic strains and poly Crystalline texture as a function of time during high-rate deformation.

TL;DR: In this paper, the authors demonstrate the use of X-ray phase contrast imaging with sub-microsecond temporal resolution to obtain quantitative visualization of dynamic fracture processes in brittle solids.

TL;DR: In this paper, the dynamic evolution of the volume fraction of extension twins in polycrystalline pure magnesium and in the AZ31B magnesium alloy, using synchrotron x-ray diffraction during compressive loading at high strain rates, was investigated.
