Texture Evolution in a Hot Rolled Austenitic Stainless Steel

The ODF analysis of the surface texture of the hot band of austenitic stainless steel reveals thepresence of orientations of shear texture. These orientation elements are mainly distributed along twolimited tubes of preferred orientations. The fibre of the first tube has its axis〈 110 〉‖ RD and runsfrom {001}〈 110 〉to an orientation near {112} 〈 110 〉whereas the fibre of the second tube is inclined30° from ND towards RD (i.e.〈 110 〉30° ND fibre) and stretches from {111} 〈 112 〉+ 5° to theorientation near {112} 〈 110 〉 . The shear texture components are formed at the surface by shearingduring hot rolling. Once they are formed, they get partly recrystallized by dynamic in siturecrystallization. On the other hand a duplex texture (i.e. retained copper type and recrystallizationtype) is present at the centre level of the hot band. The orientation elements of copper type (i.e. 〈 110 〉60° ND fibre) are {011} 〈 112 〉 , ≈ {123} 〈 634 〉and {112} 〈 111 〉whereas the recrystallizationtexture components are dominated by cube {001} 〈 100 〉orientation and other RD rotated cubesthrough oriented nucleation during dynamic recrystallization.
