In this paper, characteristics of residual stress in pearlitic steel wire drawn by a non-circular drawing (NCD)sequence with two processing routes, NCDA and NCDB, were experimentally and numerically investigated upto the 12th pass in comparison with conventional wire drawing (WD). For experimental investigation of theaxial residual stress at the surface of the drawn wire, destructive (deflection) and non-destructive methodswere employed. According to the experimental results, axial surface residual stress of the drawn wire bythe NCD sequence was lower and more homogeneous compared to the conventional WD. Based on theelasto-plastic numerical simulation results from the surface to the center of the drawn wire using a commercialDEFORM-3D, an empirical relationship between residual stress and reduction of area was determined topredict the residual stress evolution in the multi-pass WD, NCDA, and NCDB, in that order. From the resultsof this investigation, it can be construed that the NCD sequence, especially the NCDB, might be helpful inimproving the residual stress characteristics of pearlitic steel wire to improve its mechanical behavior andservice life.
