Mapping of 3D Grain Structures from Tomographic Data


Laboratory diffraction contrast tomography (LabDCT) opens up new possibilities of non-destructive 3D and time resolved 4D studies of polycrystalline material using a laboratory X-ray source. In addition to absorption contrast and phase contrast tomography, the LabDCT imaging modality spatially resolves crystallographic orientation of individual grains allowing grain shapes and boundaries of metals, alloys or ceramics to be characterized fully in 3D. Examples in both 3D and 4D will demonstrate current capabilities of the LabDCT technique for grain boundary characterization and boundary dynamics.
