However, the variation of texture and microstructure in low stacking fault energy f.c.c, metals and alloys has not been till now well recognized as investigations were generally limited to texture analysis at high rolling reductions Not enough attention has also been paid to the effect of initial texture and grain size, and to the influence of geometry of the rolling gap on inhomogeneity of texture and microstructure. Equally, the commonly used method of series expansion for the quantitative description of texture does not allow a satisfactory identification of texture details, especially in lower levels of orientation density. The orientation distribution function is then burdened with truncation errors and those ensuing from the phenomenon of ghosts; the ghosts are observed in the ODF in the positions which are in twin relations with the pronounced components, and mechanical twinning is a very important process in the deformation of low stacking fault energy metals and alloys. In the present research the rolling has been carried on with unit draughts generally not much smaller than 0.5 and not greater than 5. In these conditi.ns the texture does not exhibit the through-thickness inhomogeneity-. Texture analysis has been carried out on samples from the central layer of the rolled material when applying the direct ADC method bae on discretization, in which the above described errors do not appear For all experiments the copper 8 wt pct germanium alloy was used, rolled from the annealed state up to 98 pct reduction. In the initial state the alloy was characterized by a rather sharp texture, and the mean grain size was 95 /m. The stacking fault _energy determined by the dislocation nodes method was equal to 10 mJ/m-.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"19 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":"125230781","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}

Texture measurements were carried out on the cold rolled as well as recrystallized materials \u0000using both the conventional pole-figure and ODF (Orientation Distribution Function) methods. The \u0000results indicated the presence of a reasonably strong 〈 111 〉 ∥ ND fibre in the cold deformed alloy. The \u0000textures in the recrystallized condition were found to be basically similar to the ones for the \u0000corresponding cold deformed materials, with the difference that the pole densities were somewhat \u0000weaker in the former. A weak { 11 , 11 , 4 } fibre and a weak and incomplete { 337 } fibre have also been \u0000observed in both the cold deformed and recrystallized materials. Samples recrystallized at the lower \u0000temperature of 650℃ exhibited a sharper { 111 } texture as compared to the 800℃ annealed materials \u0000and this difference in texture intensities were perceptibly reflected in the corresponding r-values.","PeriodicalId":129427,"journal":{"name":"Textures and Microstructures","volume":"436 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":"134499023","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}
