In metallic materials the main features of a certain type of \u0000texture can clearly and comprehensively be described by using adequate extractions \u0000from the three-dimensional orientation distribution function (ODF), which is usually \u0000calculated from two-dimensional X-ray pole figures. The ODF has a higher resolving \u0000power, but the abstract form of orientation density data plotted in a three-dimensional \u0000orientation space is not always the most suitable way for presentation \u0000and further interpretation. Methods to describe the textures with the help of ideal \u0000orientations and/or fibres, their quantitative analysis with the help of Gauss-type \u0000scattering components, the selective projection and plot of characteristic orientation \u0000fibres are discussed and compared. As an example the development of rolling \u0000textures of fcc metals is described and analyzed. Using these evaluation methods it \u0000can be demonstrated how their characteristic features are related to theoretical \u0000predictions and to microstructural effects.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"1 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":"114369351","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}

The influence of the applied cyclic load on the mechanical properties of the material is of great current interest. In order to investigate residual stress evolution a series of the austenitic steel samples (X6CrNiTi1810) with different degrees of low cycle fatigue was studied. Martensitic phase formation was observed at different degrees of low cycle fatigue. Residual stresses, microstresses in both phases, as well as martensitic precipitation volume fractions, were estimated. Usually after plastic deformation the martensite phase produces a structure of oriented plates or laths. Therefore martensite texture formation during phase transition can be expected. Indeed the registered neutron diffraction spectra from austenitic fatigued samples show texture presence and its variation in dependence of the fatigue degree. The attempt to consider the texture evolution in dependence of fatigue degree and its influence on the residual stresses was made.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"44 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":"116330033","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":"Grain-Specific Texture Measurements","authors":"V. Randlè, B. Ralph","doi":"10.1155/TSM.8-9.531","DOIUrl":"https://doi.org/10.1155/TSM.8-9.531","url":null,"abstract":"In order to obtain the fullest possible picture of the interrelationship between \u0000texture, microstructure and properties it is necessary to collate data on a “microtextural” \u0000(i.e. grain specific) basis, in addition to more conventional macrotexture \u0000measurements. This paper describes two methods for the acquisition of microtextural \u0000data, the electron backscattering diffraction technique in a scanning electron \u0000microscope, and convergent beam electron diffraction in a transmission electron \u0000microscope. The former method is particularly suitable for the collection of large \u0000quantities of data, and examples of its use are included. In addition to an inverse \u0000pole figure presentation of texture, orientation measurements which arise from \u0000contiguous grains may be analysed from the standpoint of the grain misorientation \u0000texture (GMT). From this type of microtextural data the proportion and distribution \u0000of grain boundaries which possess special properties can be obtained. Since it has \u0000recently been recognised that the properties of special boundaries have a significant \u0000influence on the overall properties of the material, the ability to collect and analyse \u0000easily such data in statistically significant quantities represents an extremely powerful \u0000research technique. Finally, a method for computer generation of GMTs, both from \u0000randomly oriented and textured grain aggregates is described and compared with the \u0000experimental case.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"22 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":"123683207","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 effect was influenced by the heating rate and disappeared after decarburization. It is caused by the diffusion of Ni along the grain boundaries by which the segregation and precipitation characteristics of elements like C, N, S, is changed.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"310 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120840275","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}
