摘要: The aim of this work is to improve the hydro-formability a 409L ferritic stainless tube through treatment involving severe plastic deformation followed by annealing. For purpose, variation in determined terms parameters like circumferential R-value and elongation after application abovementioned treatment. In addition, deformation-induced surface roughening tube, called ridging, measured tension tests before Moreover, evolution texture caused studied reveal relationship between texture. results show that dramatically improves marked modification example, emergence {110}〈100〉 component present causes noticeable increase while decreasing degree ridging.
