摘要

A boron added interstitial free steel was cold rolled (CR) 90% and 98%, followed by batch annealing for different lengths of time at 650 ℃. Crystallographic textures were determined for the cold rolled, partially recrystallized and the fully recrystallized materials. The overall texture of the 98% cold rolled sample was sharper than that of the 90% cold rolled material, though both showed the presence of the gamma and the alpha fibres. Recrystallization led to a decrease in the texture intensity of the 90% cold rolled steel, while reverse was the case for the 98% cold rolled material. The r bar value of the 98% cold rolled and recrystallized steel was only marginally less than that of its 90% counterpart. Selective growth of grains with {554} <225> and {111} <123> orientations (for the 98% cold rolled material) and with {113} <471> and {223} <692> orientations (for the 90% cold rolled material) was observed after recrystallization. The Σ11 and the Σ13b CSL boundaries appeared to be involved in this process.
