Inhomogeneity of the crystallographic texture in a hot-rolled austenitic stainless steel

Abstract

The profile of the crystallographic texture through the thickness of a hot-rolled austenitic stainless steel containing 18% Cr and 8.5% Ni was examined. Although the hot-rolled strip generally revealed a weak orientation distribution, a considerable texture gradient occurred between the central layers and the surface layers. In the centre of the sheet a cold-rolling type of texture, that is, a β-fibre accompanied by a cubic orientation, was detected. It was assumed that this texture was formed during the last hot-rolling passes. Close to the surface, however, a shear texture consisting of a γ-fibre, a {{0 0 1}〈1 1 0〉 and a {1 1 2}〈1 1 0〉 component was revealed. The absence of a maximum of the shear texture at s=0.7–0.8 will be discussed in terms of the recrystallization.
