Abstract
Fine wires around the order of 0.1mm in diameter have become popular for mechanical and electrical applications. In general, fine wires produced by the drawing process are required to have both high strength and high ductility. In the wire drawing process, a large shear deformation zone with a hardened layer, referred to as the "additional shear strain layer," is generated beneath the surface layer of the wire. It is expected that this layer have high tensile strength and maintain ductility because of its fine microstructure. Hence, we investigate the effect of the additional shear strain layer on fiber texture. In summary, the crystal orientation of the surface layer is shown to be different from that of the center layer. It is confirmed that the additional shear deformation affected the fiber texture of the surface layer.
