The \u0000deformation textures were characterised by X-ray pole figures and the recrystallized grain \u0000orientations by SACP. The initial orientations were chosen to provide different types \u0000and spatial distributions of potential nucleation sites in the form of high lattice \u0000misorientation regions.In the case of 2 of the orientations, the recrystallization textures could be derived \u0000from the initial deformation textures by means of the 30-40° orientation \u0000relationship characteristic of oriented growth. These orientations, {111} and \u0000{110} do not appear to form large numbers of transition bands.However, during plane strain compression, the {001} cube orientation splits \u0000into many {012} bands misoriented by large rotations of opposite sign about TD. \u0000Subsequent recrystallization develops a strong cube texture, probably as a consequence \u0000of oriented nucleation from the relatively high density of cube oriented nuclei in the \u0000residual transition band regions. It is concluded that the controlling mechanism of \u0000recristallization texture development-oriented growth or oriented nucleation-depends upon \u0000the initial grain orientation.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"6 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":"127533844","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}
