Evolution of Texture in a Ti-IF Steel during Warm Rolling and Cold Rolling

摘要

The evolution of texture in a Ti-IF steel during the processing of ferritic hot rolling, intermediate annealing, cold rolling and annealing were studied. The texture both at the surface and mid-section for each condition were measured by X-ray and presented in the form of φ = 45° ODF sections and the so-called skeleton plots along the RD-, TD- and ND-fibers. It was found that texture characteristic at the surface is absolutely different from that at the mid-section in the hot rolled, intermediate annealed as well as in the cold rolled and annealed conditions. {110} <001> components transform to {001} <110> at the surface and {001} <110> components transform to {111} at the mid-section after intermediate annealing in this work. The intensity of a fiber at the surface as well as at the mid-section improves during cold rolling and drops during annealing, while the changing of γ fiber is not stationary during cold rolling but it absolutely intensifies after a well-advanced state of annealing.
