Abstract
This work aims to study the effect of cold forming on the texture evolution during the manufacturing of rectangular hollow sections. Conventional TMCP steel and a direct-quenched steel in 420 MPa strength level are compared. The texture was characterized at the centerline (S=0) and both surfaces (S=0.8) for base material, four flat side and one corner samples of the rectangular hollow section. The results show that the flat sides of both steels have the minor intensity of ~{554}<225> and ~{112}<110> texture components and an intense texture component of ~{001}<110> in the centerline. Generally, any significant difference between four flat size samples was not found and texture intensities of the conventional TMCP steel were slightly sharper compared to direct-quenched steel. The most important change is observed with the inner corner samples, where the randomly oriented texture in the base material and flat side samples changes to the {110}<111>/<112>> shear texture components.
