Cold drawing is an effective process to increase the strength of fully pearlitic steels with an acceptable level of ductility. Microstructural changes and deformation behavior of the pearlite during wire drawing are closely related to the initial microstructure of the pearlite. The main features of the changes while increasing drawing strain are a progressive alignment of lamellae along the drawing axis, a reduction of interlamellar spacing and a thinning of the lamellar cementite. Likewise, the behavior of the cementite dissolution would be influenced by microstructural features of the pearlite before drawing such as interlamellar spacing, colony size, etc. However, it is hard to find a report investigating the effect of microstructural features on the cementite dissolution during drawing. The purpose of this investigation is to examine the effect of microstructural features such as interlamellar spacing and colony size on the cementite dissolution during wire drawing, using Moessbauer spectroscopy, for fully pearlitic eutectoid steels.
