Being a continuous function of three variables, it requires a large number of values for its complete description. The texture can be expressed in terms of a series expansion. It then requires a large number of coefficients for its complete description. When all functional values or all coefficients are determined from experimental measurements we speak of complete texture analysis. The most important methods for complete texture analysis are individual orientation measurements of a large number of crystals and pole figure measurement followed by pole figure inversion. If only a limited number of values of the texture function or a few of its coefficients are being determined we speak of \"partial texture analysis\". The most important methods of partial texture analysis are the fixed angle texture analyzer and the measurement of the anisotropy of physical properties such as Young’s modulus magnetic properties, thermal expansion and others.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"61 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":"123162426","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}

Single crystals, consisting of the phase B2, were rolled in 11 initial orientations at 350°C with deformation degrees up to ~80%. Texture development in single crystals under rolling was analyzed to determine the acting mechanisms of plastic deformation. Three stable orientations of single crystals were found: {011}〈011〉 ,{111}〈011〉 and {111}〈112〉. It was shown on the basis of texture data, that Ti–Ni single crystals deform by means of combined action of slip in the systems {011}〈001〉 and twinning. For the first time, along with twinning in the known systems {114}〈221〉 , twinning in the systems {118}〈441〉 was revealed.

Electron microscopy offers the unique facility of diffraction from well \u0000defined locations in the sample and high resolution imaging of the microstructure. \u0000Standard techniques of orientation determination are the evaluation of electron \u0000diffraction spot and—more recently—Kikuchi patterns, which are applicable to \u0000electron transparent fine-grain materials. Specimen areas smaller than 500 nm or \u000050 nm in diameter, respectively, can be selected. Bulk samples with crystallite sizes \u0000greater than approximately 1 μm or 5 μm, respectively, can be studied with the SEM \u0000using electron backscattering or channelling patterns. For routine work a program \u0000has been developed to do on-line determination of orientation of cubic, orthorhombic \u0000or hexagonal crystals from Kikuchi, channelling and backscattering patterns.Applications of this technique on dual-phase steel are given.

This can be achieved by location-resolved diffraction of high-energy, i.e. short-wave, X-rays from synchrotron sources. Highest resolution in the orientation- as well as the location-coordinates can be achieved by three variants of a detector “sweeping” technique in which an area detector is continuously moved during exposure. This technique results in two-dimensionally continuous images which are sections and projections of the six-dimensional “orientation–location” space. Further evaluation of these images depends on whether individual grains are resolved in them or not. Because of the high penetration depth of high-energy synchrotron radiation in matter, this technique is also, and particularly, suitable for the investigation of the interior of big samples.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"727 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":"126865901","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}

{"title":"CALCULATION OF TEXTURE VOLUME FRACTIONS BY INTEGRATION AND GAUSSIAN FITTING","authors":"M. Cortie","doi":"10.1155/TSM.29.155","DOIUrl":"https://doi.org/10.1155/TSM.29.155","url":null,"abstract":"The concept of texture volume fractions has proved useful in the assessment of the \u0000orientation distributions of polycrystalline samples. Unfortunately, there is more than \u0000one method of calculating volume fractions, and the different techniques may give rather \u0000different answers. The three most commonly used methods appear to be calculation \u0000from the coefficients of the harmonic function, integration over a selected portion of an \u0000orientation distribution function (ODF), or decomposition of an ODF into component \u0000Gaussian ideal textures by a least squares fitting. The integration and Gaussian fitting \u0000methods are examined further here. In particular, the nature of the errors or differences \u0000arising from the method of integration or fitting chosen, the differing interpretations of \u0000the shape and ‘spread’ of the ideal texture, and the effect of neglecting texture components \u0000lying outside of the H0 subspace are considered. Integration of a volume enclosed \u0000by one or more cylinders defined in Eulerian space seems the most robust technique. It is \u0000usually, but not always, acceptable to neglect the effect of texture components lying \u0000outside of H0. However, it is vital that the ‘spread’ of the ideal texture component be \u0000precisely defined, and the texture volume fraction is very sensitive to the magnitude of \u0000the spread as well as to the geometric shape assumed for it.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"189 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":"115183085","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}
