Effect of Reserved Texture on Mechanical Properties of Cold Drawn Pearlitic Steel Wire

Abstract

In this paper, pearlitic steel wire with/without reserved texture were investigated with the help of mechanical test system, scanning electron microscope (SEM) and XRD. Experimental result shows that: Tensile strength of two wire are almost same. After cold drawn tensile strength of wire with reserved texture are higher than tensile strength of the without one. Before cold drawn, two wires have same microstructure of isometric pearlite and after drawing the wire with reserved texture has less shear deformed pearlitic colony. Intensity of <110> fiber texture in the wire with reserved texture are stronger than the without one at all strains. The stronger <110> texture mean the orientation of α-ferrite lamella were more closely and improve working hardening rate of pearlitic wire.
