| Abstract Scope |
After wire drawing without subsequent process steps, e.g. heat treatment, high tensile residual stresses occur on the near-surface layers. This residual stress state is unfavourable for further bending processing to produce torsion bars. In this study, a new approach to adjust the residual stress state directly in the forming process of the wire is presented. Lower tensile stress levels in the near-surface layers of the wire shall be generated by modifying the drawing tools with integrated forming elements. These elements influence the material flow and in this context the plastic deformation without affecting the designated part geometry. Based on FE-simulations the influence of the elements on the residual stress state of the wire will be identified. The experimental tests are realized and validate these results. The residual stress states of the specimens are characterized by X-ray diffraction. |
