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…
3D Mapping of Intragranular Residual Strain and Microstructure in Recrystallized Iron Using Dark-Field X-ray Microscopy
Virginia Sanna, Yubin Zhang, Wolfgang Ludwig +4
Grain growth is a key process in the thermomechanical treatment of metals. Recently, the presence of local residual stresses within fully recrystallized grains has attracted increa…
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…
