Laboratory diffraction contrast tomography (LabDCT) with a ZEISS Xradia Versa X-ray microscope 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. The unique LabDCT approach exclusively closes the gap to synchrotron 3D grain mapping techniques within laboratory research. Grain shapes and boundaries of metals, alloys or ceramics can be characterized fully in 3D. This novel non-destructive laboratory technique enables the observation and characterization of microstructural response to stimuli (stress, thermal, radiation) of one and the same sample over time. Morphological and orientation development of individual grains and their grain boundaries can be accessed and tracked. Examples in both 3D and 4D will demonstrate current capabilities of the LabDCT technique for grain boundary characterization and boundary dynamics.
