Abstract
The effect of warm rolling in the 50°C–300°C temperature range on the microstructure, stored energy and crystallographic texture of a 3 mass-% Si steel was analyzed. Both rolling and annealing texture were significantly affected by warm rolling. Dynamic strain aging (DSA) was observed in the temperature range 150°C–300°C. The stored energy, ES , of || ND oriented grains in the steel warm rolled at 200°C was found to decrease in the following order: ES > ES >> ES ≥ ES . A pronounced {110} recrystallization annealing texture was observed in specimens warm rolled in the DSA temperature range. The effect is due to the formation of {110} oriented nuclei in deformation bands occurring in || ND oriented grains after warm rolling. The deformation bands are believed to be caused by the strain localization associated with dynamic strain ageing.
