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…
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…
Laboratory Three-dimensional X-ray Micro-beam Laue Diffraction
Yubin Zhang, Anthony Seret, Jette Oddershede +9
The development of three-dimensional (3D) non-destructive X-ray characterization techniques in home laboratories is essential for enabling many more researchers to perform 3D chara…
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…
