1. X-ray diffraction microscopy is a valuable tool for microstructure characterization of polycrystalline materials.
2. Techniques such as 3DXRD and X-ray diffraction contrast tomography (DCT) can produce grain maps resolving grain-averaged orientation, shape, and strain down to a minimum grain size of a few tens of micrometres.
3. Laboratory diffraction contrast tomography (LabDCT) has been adapted to laboratory scale and made commercially available as an additional imaging modality on an X-ray microscope, using a polychromatic divergent cone beam emitted by a laboratory micro-focus X-ray source to illuminate a millimetre-sized sample.
