摘要

The texture characteristics of a Ti-IF steel in ferritic hot-rolled (warm-rolled), cold-rolled, and annealed status were studied. The hot bands were obtained by finish rolling in ferrite region, coiling at very low temperature, and then directly annealing in industrial trial. It was found that $ left{ {00 1} right}leftlangle { 1 10} rightrangle $ dominates at the surface and $ left{ { 1 1 1} right}leftlangle { 1 1 2} rightrangle $ is the main component at the midsection in the hot band. The α-fiber at the surface as well as at the midsection intensifies during cold rolling and weakens during annealing, while the changing of γ-fiber depends on the hot band texture during cold rolling, but it absolutely intensifies after a well-advanced state of annealing. Orientations concentrate on $ left{ {00 1} right}leftlangle { 1 10} rightrangle $ increasingly at the surface and continuously rotate to RD-fiber at the midsection as the reduction increases. The average plastic strain ratio, elongation, and strain hardening exponent measured for the cold-rolled and annealed steel increased with improving annealing temperatures.
