International Conference on Residual Stresses edition:9 location:Garmisch-Partenkirchen, Germany date:7-9 October 2012
Energy dispersive synchrotron diffraction has been carried out on cold drawn pearlitic
steel wires. In this paper the observed cementite peaks are analysed. For a broad range of true
drawing strains sin²(ψ) curves have been measured. The residual stress in the cementite is found to
saturate after reaching a maximum at a strain of about 1.6. No indication of significant texture
development in the cementite could be observed. An explanation is given in terms of possible
physical mechanisms. Peak broadening was observed at the early stages of deformation.
