摘要

We have addressed here the significance of high angle variant pairs with respect to Hall–Petch (H–P) relationship and plasticity, and proposed a modification to the H–P relationship based on a high-strength bainitic steel. The H–P coefficient (ky) and plasticity is closely related to the slip transmission factor (N) and the theoretical analysis indicated that the largest N values were obtained for V1/V2 and V1/V7 pairs, whereas the minimum occurred in V1/V9&19 and V1/V15&23 pairs.
