Factors influencing planar anisotropy of batch-annealed cold strip

Abstract

Based on small titanium contents, cold-rolled and batch-annealed sheet can be produced with a quasi-isotropic forming behaviour. Using the chemical composition of deep-drawing steel, the influence of low titanium contents on the deformation and recrystallization textures has been investigated. Whereas the deformation texture was not affected by the addition of titanium, the recrystallization textures showed clear differences. For example, the volume fractions of orientations corresponding to the deformation texture were increased by the addition of titanium. The recrystallization kinetics is slowed down by the addition of titanium. To achieve a low planar anisotropy, the delay of recrystallization due to Ti-alloying has to match the driving force for recrystallization, i. e. the degree of deformation
