Experimental investigation and simulation of crystallographic rolling textures of Fe–11Cr steel

Abstract

AbstractThe crystallographic hot and cold rolling textures of aferritic stainless steel containing 11 wt-%Cr were experimentally investigated using a quantitative texture analysis. For the computation of the orientation distribution function, an iterative series expansion method was employed. Both the hot and cold rolling textures revealed a texture gradient through the sheet thickness. In the centre layer of the hot band, a cold rolling type texture (αfibre)was observed which was attributed to ideal plane strain deformation and strong recovery. Close to the surface layer a strong Goss orientation was detected, which was attributed to shear deformation. During cold rolling the inherited texture sharpened in the centre layer and decreased in the subsurface layer, i.e. Goss oriented grains rotated either towards the α fibre or towards {1ll} 〈112〉. The evolution of the cold rolling texture was simulated by use of a Taylor type model based on the knowledge of the starting texture and grain morphology.MST/13134
