Abstract

The ODF analysis of the surface texture of the hot band of austenitic stainless steel reveals the presence of orientations of shear texture. These orientation elements are mainly distributed along two limited tubes of preferred orientations. The fibre of the first tube has its axis 110 ‖ RD and runs from {001} 110 to an orientation near {112}110 whereas the fibre of the second tube is inclined 30° from ND towards RD (i.e. 110 30° ND fibre) and stretches from {111}112 + 5° to the orientation near {112}110. The shear texture components are formed at the surface by shearing during hot rolling. Once they are formed, they get partly recrystallized by dynamic in situ recrystallization. On the other hand a duplex texture (i.e. retained copper type and recrystallization type) 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 recrystallization texture components are dominated by cube {001}100 orientation and other RD rotated cubes through oriented nucleation during dynamic recrystallization.
