Samples of the ferrimagnetic material Ba3Co2Fe24041, pre-aligned in a magnetic field and sintered at various temperatures, have been examined for preferred orientation. Schulz's reflexion technique and the standardizing method of Holland were used to determine quantitative pole figures of several lattice planes. The texture bears a close resemblance to a 'fan texture' in which the crystallites have their basal planes parallel to a preferred direction. The sharpness of the texture increases with increasing sintering temperature. At 1320°C an exaggerated grain growth takes place. Inhomogeneity of the magnetic field throughout the sample results in local differences in orientation.243
Gypsum was set on polyethylene foil of different origin and on cellophane foil. Experiments were also carried out in an electric field (5-25 kV direct-current). In all cases (especially in the electric field) (010) textures developed on the contact surfaces and were overlapped by a (121) texture. Brinell hardness tests show a greater hardness of the contact areas than those of the upper sides of the samples. Those samples set in an electric field yielded, partly, greater differences. The values, however, diverge greatly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
