Frontiers in Non-Destructive 3D Grain Mapping in the Laboratory

View Full Event Details

X-ray tomography for 3D non-destructive imaging has been widely adopted and operated under two primary contrast mechanisms for quite some time: X-ray absorption and phase contrast, which both rely on material density differences within the sample. Synchrotron-based X-ray imaging methods – such as diffraction contrast tomography (DCT), which provide crystallographic information from the diffraction signals of polycrystalline samples, non-destructively and in three dimensions (3D) – were the first to successfully demonstrate results in polycrystalline materials almost two decades ago.


This seminar will present the latest capabilities of laboratory-based DCT. It will cover the recently introduced advanced diffraction scanning modes that address the challenge of achieving true sample representivity by investigating massive volumes of samples at an unprecedented scale. It will further demonstrate applications use cases of extremely large volume grain mapping on a wide variety of materials ranging from metals, ceramics and geomaterials. Finally, it will present some unique correlative workflows spanning across X-ray microscopy, non-destructive grain mapping combined with high resolution scanning electron microscopy to get valuable insights into the multiscale material microstructure.
