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…
Operando observation of strain relaxation in fatigued pearlitic steel
Louis Lesage, Johan Ahlström, Yubin Zhang +1
Pearlitic steels are the material of choice for railway wheels and rails, where their lamellar ferrite-cementite structure balances cost, strength, and wear resistance. However, in…
Geometrically necessary boundaries accommodate the residual elastic strain in cold-rolled Fe-3%Si
Aditya Shukla, Nikolas Mavrikakis, Can Yildirim
The relationship between plastic deformation accommodation structures and residual elastic strain fields in deformed metals is poorly understood at the intragranular scale, largely…
Diamond compound refractive lenses for high energy Dark Field X-ray Microscopy
Steffen Staeck, Can Yildirim, Frank Seiboth +4
Compound-refractive lenses (CRL) are a type of x-ray optics that find widespread applications as focusing and imaging lenses. The choice of material is one of the most defining pro…
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…
Revealing 3D orientation and strain heterogeneity in calcite generated by bio-cementation
Marilyn Sarkis, James A. D. Ball, Michela La Bella +5
Bio-cementation uses bacterially induced calcite to bind sand grains, offering a low-carbon approach to soil stabilization. However, the 3D morphology, orientation texture, and int…
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…
Remanent crustal strain on Mars in non-poikilitic olivine of NWA 7721
Yaozhu Li, Szilvia Kalácska, Phil McCausland +5
We present a multiscale microstructural analysis of olivine from the non-poikilitic lithology of the poikilitic shergottite NWA 7721, using dark-field X-ray microscopy (DFXM), elec…
Quantifying Resolution in Pink Beam Dark Field X-ray Microscopy: Experiments and Simulations
Michela La Bella, Henning Friis Poulsen, Steffen Staeck +4
Pink-beam Dark-Field X-ray Microscopy (pDFXM) is a powerful emerging technique for time-resolved studies of microstructure and strain evolution in bulk crystalline materials. In th…
Bridging Grain Mapping and Dark Field X-ray Microscopy for Multiscale Diffraction Imaging
Aditya Shukla, Can Yildirim, James A. D. Ball +7
Resolving how defects emerge and interact within the hierarchical structure of polycrystalline materials remains a core challenge in materials science. Grain-mapping methods such a…
A high-temperature furnace for multi-modal synchrotron-based X-ray microscopy and diffraction imaging
Louis Lesage, Yves Watier, Helena Isern +6
The design, calibration, and initial application of a non-contact high-temperature furnace developed for in situ synchrotron X-ray experiments are presented. The system enables a s…
Pink-Beam Dark Field X-ray Microscopy: Expanding 3D/4D Imaging for Complex and Deformed Microstructures
Can Yildirim, Aditya Shukla, Yubin Zhang +8
Dark Field X-ray Microscopy (DFXM) has advanced 3D non-destructive, high-resolution imaging of strain and orientation in crystalline materials, enabling the study of embedded struc…
Three-dimensional nucleation and growth of deformation twins in magnesium
Sangwon Lee, Michael Pilipchuk, Can Yildirim +9
At two-thirds the weight of aluminum, magnesium alloys have the potential to significantly reduce the fuel consumption of transportation vehicles. These advancements depend on our…
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…
