Abstract

Microstructural inhomogeneities in polycrystalline copper was intentionally varied by the deformation at the liquid nitrogen temperature and the rolling without lubrication. The effect of different rolling conditions on the evolution of microstructure and texture during rolling and subsequent recrystallization was studied by means of X-ray texture measurement and microstructural observations. Applying cold rolling at a low temperature led to the formation of deformation twins in grains at the Cu-orientation, and shear bands developed when cold rolling was performed without lubrication. The evolution of the normal rolling texture was suppressed by deformation twinning. Shear bands in deformed structure resulted in a very weak cube-recrystallization texture.
