After 70% compression, the average number of deformation bands per grain increases from \u000016 to 36 as the deformation temperature increases from 25 to 300℃. An orientation dependence of \u0000banding tendency is also observed. Grains with near {110} orientation are found to have the lowest \u0000banding tendency. The textures of samples compressed below 300℃ are similar and consist mainly \u0000of a {110} fibre and a weak {100} fibre. While the {110} component remains when deformation \u0000temperature is increased to 300℃; the {100} component becomes weaker. 300℃ is in fact the temperature at which large scale dynamic recrystallisation occurs. It is suspected that the decay of the \u0000{100} component is due to dynamic recrystallisation which takes place preferentially at thin deformation \u0000bands where most of the {100} oriented material is found.","PeriodicalId":413822,"journal":{"name":"Texture, Stress, and Microstructure","volume":"31 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":"132865336","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}

Hot band samples with grain sizes of 8 and 47 µm were used and rolling was carried out to reductions of 70% and 85%. Two levels of solute carbon were obtained prior to cold rolling by quenching and overaging. Recrystallization textures were measured following single and two step isothermal annealing treatments. In the latter, the level of solute carbon is lowered prior to the commencement \u0000of recrystallization. For the single step treatment, the {111} texture intensity was lower in all the samples that had a high level of solute carbon present during rolling.
