Web3.3.3 Preferred orientation of grains. Preferred orientation, also known as crystallographic texture, means that a certain proportion of grains in the material would crystallographically orient themselves within a narrower orientation range than the neighboring grains. Ductile materials used in magnetron sputtering show some degree of … WebNov 28, 2024 · The crystal preferred orientation (CPO) of amphibole has a large effect on seismic anisotropy in the crust. In many previous studies on natural amphibolites, four amphibole CPO types (types I–IV)...
Epitaxial Growth and Stray Grain Control toward Single‐Crystal …
WebDetermination and interpretation of the preferred orientation of crystals in deformed polycrystalline aggregates (in this volume also referred to as texture) has been of longstanding concern to both materials scientists and geologists. A similar theoretical background--such as the dislocation theory of crystal WebMar 14, 2024 · As mentioned in Section 2, the preferred condition for ensuring epitaxial growth is higher thermal gradient G and lower solidification rate V. Thus, aside from the managing laser scanning direction to coordinate with substrate crystallographic orientation, applying extra cooling on the substrate seems viable for promoting epitaxial grain growth ... opus inspection logo
