Automated Burgers Vector Identification for Individual Dislocations in Bulk Crystals
Abderrahmane Benhadjira, Carsten Detlefs, Vincent Favre-Nicolin +4
Weak-beam imaging in dark-field X-ray microscopy (DFXM) can resolve individual dislocations in bulk crystals, but assigning Burgers vectors from the resulting contrast typically re…
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 +3
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…
Observing formation and evolution of dislocation cells during plastic deformation
Albert Zelenika, Adam André William Cretton, Felix Frankus +6
During plastic deformation of metals and alloys, dislocations self-organise in cells, which subsequently continuously decrease in size. How and when these processes take place has…
