Residual stress in pearlitic steel rods during progressively cold drawing measured by X-ray diffraction

This research aims to investigate the residual stress evolution in pearlitic steels during progressively cold drawing. To this end, pearlitic steel rods of 13 mm diameter are continuously cold-drawn to wires of 5.3 mm, and then the residual stresses of multi-pass drawing rods are evaluated by X-ray...

Description
Summary:This research aims to investigate the residual stress evolution in pearlitic steels during progressively cold drawing. To this end, pearlitic steel rods of 13 mm diameter are continuously cold-drawn to wires of 5.3 mm, and then the residual stresses of multi-pass drawing rods are evaluated by X-ray diffraction technique. The XRD results indicate that the residual stresses of pearlitic steel rods increase gradually with the growing of drawing strain, from stress-free of original rod to high tensile stress of 650 MPa in the last pass drawing wire.
