This method is based on the fact, that one gets etch patterns characteristic for the \u0000crystallographic orientation of the etched surface, if a specimen of copper or copper alloys is etched \u0000in conc. HNO3. In contrast to etch pits, the etch patterns are developed continuously over the whole \u0000grain. This allows a direct and continuous observation of the orientation changes within and between \u0000the grains, which is not possible for many other orientation determination methods. The determination \u0000accuracy of the new method depends on the crystallographic orientation of the etched surface and varies \u0000between 2° and 10°. For some special surface orientations the etch patterns allow even the determination \u0000of very small orientation changes (≤ 2°), occurring e.g. in a deformed grain.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122495607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This loss, caused by Larmor precession in individual domains, determines the mean domain size, the mean square direction cosines of the domains and the mean magnetization. The method is complementary to the neutron scattering technique with respect to the size of the inhomogeneities to be determined and the dynamic range accessible. Only the static applications of the method in studying domain structures are considered. As examples will be treated metal foils under stress, oriented ferroxdur permanent magnets, soft ferrites, recording tapes and thin films. In most of these examples magnetic correlations between neighbouring domains are subject of study.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117095349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Calcite shows a c-axis maximum \u0000rotated against the shear sense with regard to the main shear plane. In contrast, the \u0000dolomite shows a c-axis maximum rotated with the shear sense. In accordance with the \u0000experimental and simulated textures from the literature, this difference proves e-twinning \u0000and r-slip for calcite and f-twinning and c-slip for dolomite as the main deformation \u0000mechanisms. The dolomitic calcite mylonite shows for both the calcite and the dolomite a \u0000c-axis maximum rotated against the shear sense.

In case of the cold forward extruded samples at low degrees of natural strain, the rod kernel is under compressive residual stresses which are balanced by tensile residual stresses in the outer part of the sample. In contrast to this, the outer part of the hot extruded sample is under compressive macroscopic stresses which are balanced by tensile macroscopic residual stresses in the inner part of the sample.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126667723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
