Title: 3-dimensional characterization of polycrystalline bulk materials using high energy synchrotron radiation

Abstract

The implementation of 3-Dimensional X-Ray Diffraction (3DXRD) Microscopy at the Advanced Photon Source is described. The technique enables the non-destructive structural characterization of polycrystalline bulk materials and is therefore suitable for in situ studies during thermo-mechanical processing. High energy synchrotron radiation and area detectors are employed. First, a forward modeling approach for the reconstruction of grain boundaries from high resolution diffraction images is described. Second, a high resolution reciprocal space mapping technique of individual grains is presented. The microstructure of polycrystalline materials is characterized by a hierarchical arrangement of crystalline elements (grains, microbands, and subgrains). The arrangement is often highlyheterogeneous, especially with respect to the dynamics during processing. Conventional experimental methods either lack sufficient spatial resolution or are surface or thin foil probes, which require samples to be sectioned before investigation to obtain spatially resolved results representative of bulk behavior. This destructive procedure prohibits studies of the dynamics of the individual elements. Thus, there is a need for a nondestructive method that provides comprehensive structural information for each of the crystalline elements within macroscopic volumes of the material. Furthermore, the method should be sufficiently fast to record the dynamics of 10-1000 elements simultaneously during processing.
