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…
