Development of cold rolling and intercritical annealing texture in two TRIP-aided steels

High strength TRIP-aided steel sheets with high formability and better ductility are of industrial interest. Texture control and retained austenite characterization are considered as the main factors with respect to the formability and ductility. In this work, the effect of cold rolling and intercritical annealing on texture development has been investigated for two TRIP-aided steel sheets, which are different in Si and A1 content. Experiments show that the cold rolling extends the alpha and gamma-fibers on these grades of steel. Intercretically annealing decreases the intensity of alpha-fiber and leads to sharpness of gamma-fiber, especially for A1 steel.
