| Abstract Scope |
In this talk, we will cover the basic principles governing x-ray Bragg coherent diffraction imaging at modern synchrotron light sources that enable structural heterogeneities of polycrystalline materials to be imaged at the nanoscale. This capability, combined with the penetrating power of hard x-rays, provides an opportunity to image the response of materials in environments pertinent to applications and revealing of fundamental connections between nanoscale distributions of lattice strain, defects, and domain boundaries and materials properties. Advances of Bragg coherent diffraction imaging will be discussed especially in the very hard x-ray regime (>50keV) where concurrent measurement alongside more well-established High Energy Diffraction Microscopy methods is viable and has been demonstrated by our team. This possibility is now afforded by the upgrade of the Advanced Photon Source.
