WebSep 26, 2016 · At misorientations ϑ above ∼15°, γ takes on an approximately constant value, except near special coincident site lattice (CSL) boundaries. For two crystallites with initial misorientation ϑ 1 < 15 °, a relative rotation to ϑ 2 < ϑ 1 leads to a significant reduction in γ, owing to the gradient d γ / d ϑ. Open in viewer WebApr 1, 2024 · A crystallographic misorientation is the 3D rotation between any two selected crystal orientations. Each misorientation rotation can be described by an axis of rotation and an angular magnitude of rotation about that axis. For each quartz grain in the WISZ samples, we calculate the misorientation between every measured lattice …
