Non-homogeneity of recrystallization texture in polycrystalline copper

Abstract

The correlation of non-homogeneity of texture in cold-rolled copper (99·9%purity) with that in recrystallized copper is described. A high degree of non-homogeneity of texture was obtained in the metal by a suitable rolling up to 90% deformation. The copper type of rolling texture appeared in the centre while the shear type was observed in the surface layer. By annealing between 700° and 900°C, a sharp cube texture and a small amount of texture similar to that observed in the deformed state were developed in the centre. The recrystallization type of texture appeared in the surface layer of the sample with an approximately 56° rotation about the common <111> directions of the suitable shear-texture components and was described as the {323}<101> orientation rotated by 7° about the transvere direction.
