Revealing Dislocation Interactions Controlling Mechanical Properties of Metals
Felix Frankus, Sina Borgi, Albert Zelenika +4
During plastic deformation, metals change shape while continuously becoming stronger. The microscopic origin of these processes lies in the proliferation and movement of line defec…
FaCT-GS: Fast and Scalable CT Reconstruction with Gaussian Splatting
Pawel Tomasz Pieta, Rasmus Juul Pedersen, Sina Borgi +4
Gaussian Splatting (GS) has emerged as a dominating technique for image rendering and has quickly been adapted for the X-ray Computed Tomography (CT) reconstruction task. However,…
Deep Learning-Assisted Weak Beam Identification in Dark-Field X-ray Microscopy
A. Benhadjira, C. Detlefs, S. Borgi +2
Dislocations control the mechanical behavior of crystalline materials, yet their quantitative characterization in bulk has remained elusive. Transmission Electron Microscopy provid…
Oblique diffraction geometry for the observation of several non-coplanar Bragg reflections under identical illumination
C. Detlefs, A. Henningsson, B. Kanesalingam +9
We present a method to determine the strain tensor and local lattice rotation with Dark Field X-ray Microscopy. Using a set of at least 3 non-coplanar, symmetry-equivalent Bragg re…
Towards Interfacing Dark-Field X-ray Microscopy to Dislocation Dynamics Modeling
Axel Henningsson, Sina Borgi, Grethe Winther +2
Deformation gradient tensor fields are reconstructed in three dimensions (mapping all 9 tensor components) using synthetic Dark-Field X-ray Microscopy data. Owing to the unique pro…
