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…
Spatially resolved elastic strain and lattice rotation at threading dislocations in HgCdTe/CdZnTe epilayers by dark-field X-ray microscopy
C. Yildirim, A. Benhadjira, P. Ballet +5
Threading dislocations (TDs) propagating from a CdZnTe (CZT) substrate into a liquid-phase-epitaxy HgCdTe (MCT) epilayer set the minority-carrier lifeti…
Multilayer Laue Lenses for Enhanced Spatial Resolution in Dark-Field X-ray Microscopy
Steffen Staeck, Can Yildirim, Raquel Rodriguez-Lamas +5
We introduce the use of a crossed pair of Multilayer Laue Lenses (MLLs) as an objective in Dark-Field X-ray Microscopy (DFXM). In a demonstration experiment at the ID03 beamline at…
Unexpected Planar Dislocation Boundary Formation in FCC Metals Captured by Dark-Field X-ray Microscopy and Continuum Dislocation Dynamics
Adam André William Cretton, Khaled SharafEldin, Axel Henningsson +8
Validating dislocation patterning models against in situ imaging experiments is a longstanding goal in materials physics. Here, we provide the first direct morphological comparison…
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…
The ESRF dark-field x-ray microscope at ID03
H. Isern, T. Brochard, T. Dufrane +9
Dark Field X-ray Microscopy (DFXM) is a full-field imaging technique for non-destructive 3D mapping of orientation and strain in crystalline elements. The new DFXM beamline at ID03…
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…
3D Microstructural and Strain Evolution During the Early Stages of Tensile Deformation
Albert Zelenika, Can Yildirim, Carsten Detlefs +4
Dislocation patterning and self-organization during plastic deformation are associated with work hardening, but the exact mechanisms remain elusive. This is partly because studies…
