Abstract

A novel texture, which improves Young’s modulus in rolling direction, has been found in a hot rolled low carbon sheet steel. This unique texture is observed in sheet surface area, which consists of sharply developed {110}<111>–{110}<112> fiber without {110}<001>. Together with {112}<111> orientation, this fiber can significantly contribute to increase Young’s modulus in rolling direction. The measured Young’s modulus in rolling direction in the present material is 236 GPa, which is more than 10% increase, compared to the one in conventional steels.

Hot rolling texture observed at (a) mid-plane of specimen A, (b) 1/8 plane of specimen A, (c) mid-plane of specimen B and (d) 1/8 plane of specimen B. Fullsize Image
