Abstract
The texture difference between the center and sub-surface of pearlitic steel wires, which were manufactured by continuous cold drawing, was investigated by orientation distribution function based on electron back-scattered diffraction at different drawing passes. A perfect 〈110〉 fiber texture parallel to drawing direction develops gradually with drawing strain increasing at the wire center, while at the sub-surface, a quasi 〈110〉 fiber texture with the 〈111〉 orientation nearly parallel to the circumferential direction is found. This texture at the sub-surface is softer than the perfect 〈110〉 fiber texture in tension. The reasons for this texture difference and influences on the wire’s mechanical properties are discussed.
