Progressive changes in the microstructure and texture in pearlitic steel during wire drawing

Abstract

The evolution of microstructure and texture during wire drawing of pearlitic steel was studied using scanning electron microscopy and X-ray diffraction. Wire drawing induces elongation of ferrite grains with the development of <110> fibre texture. The cementite lamellae also have a tendency to reorient themselves along the wire axis with increasing strain. Viscoplastic self-consistent simulations were employed to simulate the texture evolution in the ferrite phase. © 2011 ISIJ.
