Abstract

ARMCO-iron was cross-rolled in two different modes, i.e. with a rotation of the rolling direction through 90° after each individual pass or after half of the reduction in thickness only. In the first case, which corresponds to a truly tetragonal straight deformation path, the orientation {001}110 assumes an extremely high orientation density of 50 × random after 93% reduction. Besides this, the texture contains a nearly ideal 111‖ND-orientation tube, the intensity of which increases to about 10 × random. The texture of the second mode is similar to that of the first one up to about 50% reduction. After that the density in the orientation {001}110 decreases and increases again at the highest deformation degrees. Two minor orientation components {001}100 and {011}100 were found with intensities in the range of 3 to 5 × random at low deformation degrees of about 10%.
