WebIn materials science, misorientation is the difference in crystallographic orientation between two crystallites in a polycrystalline material.. In crystalline materials, the orientation of a crystallite is defined by a transformation from a sample reference frame (i.e. defined by the direction of a rolling or extrusion process and two orthogonal directions) to the local … WebFeb 28, 2024 · The misorientation axes of adjacent crystals show an approximately random distribution. Rothpletzella also shares morphological similarities with extant cyanobacteria. ...
