Abstract: This study demonstrates the influence of residual stresses in steel wires on the stress relaxation losses.
Standard stress relaxation tests were performed on four types of wire, all with the same mechanical properties but with different residual stresses.
Surface residual stresses were measured by X-ray diffraction.
The experimental results show that stress relaxation losses decrease as the value of surface tensile residual stresses decrease.
The role, sometimes controversial, of initial pre-stretching and heat treatments on stress relaxation losses can also be understood in the light of the residual stresses induced during cold-drawing.
