By using three dimensional X-ray microdiffraction technique, local crystallographic orientation of submicron volumes within polycrystalline materials will be determined, and the grain boundary type be identified within the framework of an ideal coincident site lattice model. We hope this new approach to grain boundary characterization can address long-standing questions about grain boundary networks in materials and can now provide quantitative tests of grain boundary models with new insights for grain boundary engineering efforts. equipment_required: experiment: Characterization of grain boundary network by X-ray microdiffraction foreign_nationals: hazards: Only couple of Ni or Al etc samples will be measured.
