Crystallographic textures
To material scientists the term texture means the crystallographic orientation of grains in a polycrystal. In contrast, geologists use the term more generally to refer to the spatial arrangement or association of mineral grains in a rock. In this contribution we are concerned with the materials science definition. There are several established techniques available for the determination of cryst...
متن کاملNanoscale crystal imperfection-induced characterization changes of manganite nanolayers with various crystallographic textures
(La,Sr)MnO3 (LSMO) nanolayers with various crystallographic textures were grown on the sapphire substrate with and without In2O3 epitaxial buffering. The LSMO nanolayer with In2O3 epitaxial buffering has a (110) preferred orientation. However, the nanolayer without buffering shows a highly (100)-oriented texture. Detailed microstructure analyses show that the LSMO nanolayer with In2O3 epitaxial...
متن کاملCrystallographic Textures and Morphologies of Solution Cast Ibuprofen Composite Films at Solid Surfaces
The preparation of thin composite layers has promising advantages in a variety of applications like transdermal, buccal, or sublingual patches. Within this model study the impact of the matrix material on the film forming properties of ibuprofen-matrix composite films is investigated. As matrix materials polystyrene, methyl cellulose, or hydroxyl-ethyl cellulose were used. The film properties w...
متن کاملEFFECT OF CRYSTALLOGRAPHIC AND MORPHOLOGIC TEXTURES ON THE ANISOTROPY OF MECHANICAL PROPERTIES OF Al-Li ALLOYS
A new formulation of the self consistent model has been applied to predict the plastic behaviour of A1-Li Alloys. This model enables to take into account simultaneously the crystallographic texture, the morphology of grains, the internal stresses evolution and the anisotropy of intracrystalline hardening. Microscopic observations and analyses of crystallographic textures are used t o constitute...
متن کاملHopf Textures
A Hopf texture is a vacuum field configuration of isovector fields which is an onto map from the space as a large three sphere to the vacuum manifold S. We construct a Hopf texture with spherically symmetric energy density and discuss the topological charge. A Hopf texture collapses, and we study the collapse process numerically. In our simulations, it is clear that a Hopf texture does not deca...
