Abstract
There is a possibility that even a micro flaw on the wire surface will cause a fatal defect in a product for using automobile and machine. The deformation of these defects is not clarified during processing yet. In this study, the authors artificially produced scratches on the surface of wires, and investigated the growth and disappearance of these cracks during drawing, by three-dimensional FEA and experiments. A scratch on the wire surface appears to be removed after repeated drawing. However, in actuality, the flaw remains inside the wire because of the development of an overlap, and thus it is difficult to completely removed the flaw. Moreover, the influence which the surface treatment of peeling has on a wire rod, was considered. Superior wires without flaws could be obtained by removing the flaws before drawing and by multi-pass drawing.
