Title: Three-dimensional high-energy diffraction microscopy of polycrystalline bulk materials.

Abstract

The microstructure of polycrystalline materials is characterized by a hierarchical arrangement of crystalline elements (grains, microbands, and subgrains). The arrangement is often highly heterogeneous, especially with respect to dynamics during processing. Conventional experimental methods either lack sufficient spatial resolution or are surface or thin foil probes. To obtain three dimensional spatially resolved results with these latter techniques requires that samples be sectioned. This destructive procedure prohibits studies of the dynamics of the individual crystalline 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. Three-dimensional x-ray diffraction (3DXRD) microscopy is an emerging method that aims to fulfill these requirements. The method is distinguished by two principles. The first is the use of a beam of high-energy x-rays generated by a synchrotron source for transmission studies. Hard x-rays (in the range 50-100 keV) can penetrate 4 cm of aluminum or 5 mm of steel. The second principle is a 'tomographic' approach to diffraction. The conventional approach for providing spatially resolved information with diffraction is to scan themore » sample with respect to the beam. However, probing the sample point-by-point is generally too slow for dynamic studies. Hence, it has been replaced by an approach that provides information on many parts of the material simultaneously. Here we report on activities establishing 3DXRD capabilities at The Advanced Photon Source (Argonne National Laboratory) within the high-energy program at beamline 1-ID.« less
