Abstract
The cold drawing pearlitic steel wires are widely used in industry such as the automobile tire and ropes. And it possesses an ultra high strength, almost the highest in all the steel products. So many investigations are focused on the hardening mechanisms of pearlitic steel wire during cold drawing, including the microstructure fining, texture evolution and cementite dissolution. In this study, the electron backscatter diffraction (EBSD) and the visco-plastic selfconsistent (VPSC) model are used to investigate the texture evolution law at the center of wire during the drawing, as well as its influences on the mechanical behaviors. The EBSD results show that the asreceived wires after dry drawing and quenching have a little fiber texture along the drawing direction. And with wet drawing strain increasing, the intense of fiber texture increases apparently.
