Circular Texture of Drawn High-Carbon Steel Wire for Tire Cord

타이어 코드용 고탄소강선의 원형집합조직

The texture of a 0.25mm dia high-carbon(0.73%) steel wire made by drawing the patented and brass coated 1.4mm wire through 22 dies with a die-angle of 12$^{\circ}$has been measured. The ideal fiber texture was obtained in the center layer, while the circular texture and the near fiber texture having {111}<110> and weak {112}<110> components were obtained in the intermediate and surface layers, respectively. The circular texture was approximated by {110}<110> plus {110}<114>. The texture could be predicted by the Taylor-Bishop-Hill theory coupled with FEM for deformation.
