Hence, five-dimensional boundary distribution functions have to be considered. If one considers only misorientation a three-dimensional \u0000misorientation distribution function is obtained. The deviation of this function from the #8220;uncorrelated” misorientation distribution yields the orientation correlation function. The most economical representation of these functions is the one using series expansions in terms of symmetrized harmonic functions. With the present state of experimental technique it seems to be impossible to determine the complete boundary distribution functions. However, two-dimensional analoga of these functions can be obtained from electron diffraction measurements.","PeriodicalId":413822,"journal":{"name":"Texture, Stress, and Microstructure","volume":"30 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":"127636592","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}

May and Turnbull2 showed that the second phase particles, particlarly MnS influence the mobility of the boundaries. Later Misra, Dfirman and Lficke3, as well as Inokuti4 found a strong correlation between the strength of the Gosscomponent measured in the subsurface of the hot band and that of the final product. Evidence was also given to indicate that the final Goss texture formation may also occur when the hot band subsurface contained no Goss at all5. Haratani and Hutchinson6, on the other hand, based on a series of sectioning experiments of silicon steel taken at various stages between primary recrystallization and subsequent abnormal grain growth, found that shear bands of {111}<112> orientation serve as nuclei for the Goss texture formation in the primary recrystallized specimen. Another series ofresearch by Harase and coworkers7 followed the idea ofAust and Rutter8, that boundaries with a high number of coincidence site lattice points migrate with a rate higher than others. First Harase et al.6 then Rouag et al.9 have observed that the formation of a well aligned Goss texture with little scatter, observed after abnormal grain growth, can be linked to the P.(9) type CSL boundaries in the primary recrystallized structure. For some time it was evident that it is not possible to accept several differring and contradictory explanations for the same final texture development, unless these theories are rather complementary then contradictory. We shall, in this paper, show that linking the hypotheses stated above can contribute to the understanding of the final texture development in GO silicon steel.","PeriodicalId":413822,"journal":{"name":"Texture, Stress, and Microstructure","volume":"27 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":"126677961","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}

They were also calculated on the basis of X-ray texture measurements using the Hill approximation. The maximum deviation between experimental and calculated values is 3.5%. An influence of the slightly anisotropic grain structure on the elastic anisotropy could not be seen. and position of each crystallite is known, then the boundary conditions in the grain boundaries can be strictly taken into account and the polycrystal properties can be calculated straight foreward. However, this is usually not the case. Certain statistical assumptions must then be made which lead to various approximative models for the polycrystal constants. In the Reuss model (Reuss, 1929), constant stress is assumed whereas the Voigt model (Voigt, 1928) assumes constant strain throughout the polycrystal. The polycrystal constants are then the simple volume averages of the components of the stiffness and compliance tensor of the individual crystallites, respectively. These assumptions are limiting cases, the actual values must lie between them. In a first approximation, knowing nothing about the microstructure, the average of both these assumptions can be taken, corresponding to the Hill approximation (Hill, 1952). It has been found that this approximation, although theoretically unsatisfactory, agrees with the experimen- tal results within a few percent, which is sufficient for most practical purposes. A theoretically much more satisfactory model was developed by Kr6ner (Kr6ner, 1958). In this model a spherical grain is embedded in a polycrystalline matrix","PeriodicalId":413822,"journal":{"name":"Texture, Stress, and Microstructure","volume":"12 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":"121331830","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}
