abstract = {Residual stresses caused by different deformation steps during the processing of wires significantly affect the mechanical properties of the final product. However, in the literature, there is a lack of detailed information about their correlation with mechanical properties. Therefore, the proposed work focuses on the influence of tempering on the macro- and micro-residual stresses, and related mechanical properties of a ferritic-pearlitic 27MnSiVS6 steel wire in the deformed state after hot rolling, drawing, coiling, and straightening. Characterization of the wire in the deformed state indicates macro-residual stresses that remain high after tempering at a temperature of 400 °C for 10 minutes and decrease significantly after tempering at 475 °C for 10 minutes. In situ high-energy X-ray diffraction measurements during heating of wires in the deformed state reveal that micro-residual stresses remain unchanged up to temperatures of 200 °C, while they decrease at 300 °C. Investigations of the mechanical properties show that a reduction of micro-residual stresses correlates with a reduction of the curvature of the stress–strain curve below the yield point, which increases the yield stress. Conversely, the reduction of macro-residual stresses begins in the temperature regime of recovery and relaxation, where a reduction of yield stress and tensile strength occurs.},
