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…
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…
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…
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…
