Surface Texture of Deformed Copper Wire

Abstract

Abstract The texture of the cold-drawn copper wire was investigated along the radius and on surface by means of EBSD. The wire fiber texture after drawing has been shown to consist of a set of a main orientations analogically to the rolling texture. These texture orientations are associated to the stress state in drawing. The central area of the wire was characterized by two main orientations: faint <001> and powerful <111>-fibers. Main orientations {110} <001> and {112} <111> were distinguished within these fibers. The peripheral region is represented by a shear texture that rotates 90° to the center texture and scattered at ± 10°. The surface texture scattered close to axial and also has deviated preferred components: strong {110} <001> and weak {112} <111> orientations.
