Microstructural and textural development in an extra low carbon steel during warm rolling

An attempt has been made to study the development of microstructure and texture in an extra low carbon steel warm rolled by ∼80% in a single pass at four different temperatures. The γ fibre texture develops at lower warm rolling temperatures (500 and 600 °C) and a very weak α fibre develops at higher rolling temperatures (700 and 800 °C). These observations have been correlated with the occurrence of static recrystallization at higher rolling temperatures and with the formation of high densities of the deformation bands (DB) in the deformed microstructures of samples rolled at lower temperatures.
