Abstract Scope |
The synchrotron-based 3D X-ray diffraction technique known as high-energy diffraction microscopy (HEDM) can be used to nondestructively measure 3D microscale information including the elastic strain tensor, crystallographic orientation, location, and volume of each grain for many hundreds to thousands of grains. For this reason, HEDM is arguably one of the most powerful experimental tools we have for mapping the interplay between micro- and macroscale material behavior. Currently, HEDM is only available at select synchrotrons around the world. Here, we present a laboratory-scale HEDM instrument that utilizes an indium liquid-metal jet X-ray source to produce a monochromatic 24 keV parallel box beam suitable for near-field and far-field HEDM measurements on bulk (~1 mm) single crystal, polycrystalline, or granular materials, particularly those composed of light elements (e.g., Al, Mg, Li). We discuss the design and construction of this instrument and present preliminary results. |
