利用电子背散射衍射技术对高碳钢盘条冷拉拔过程中的织构、泰勒因子和取向差演变进行了表征，根据泰勒因子的变化解释了织构的演变过程，讨论了演变机制，同时，也初步研究了取向差的相关联和非相关联分布。结果表明：随着拉拔应变量的增大，盘条中泰勒因子统计平均值大于3的晶粒所占比率逐步增加，说明在连续冷拉拔过程中，〈113〉丝织构向〈110〉丝织构发生了转变；珠光体团明显变形，导致小角度晶界数量显著增多；当应变量较小时，非相关联分布与Mackenzie分布一致；当应变量较大时，非相关联取向差分布图在20°和55°附近均出现峰值，反映出位错增殖和小角度晶界向大角度晶界发生了转变。

The evolution of texture, Taylor factor and disorientation of high carbon steel wire rod during cold drawing was characterized using electron backscatter diffraction. The texture evolution was interpreted in terms of variation of Taylor factor and the mechanism of the evolution was discussed. Meanwhile, the evolution of correlated and uncorrelated distribution of disorientation was preliminarily studied. The results show that with the increase of drawing strain, the relative content of grains with Taylor factor greater than 3 increased, indicating that the 〈110〉-fiber texture changed from the 〈113〉-fiber texture during the successive drawing. Meanwhile, the pearlite colonies were evidently deformed, resulting in the amount of low angle grain boundary increasing. The uncorrelated distribution of disorientation coincided with Mackenzie distribution under relatively small strains, while peaks appeared both at 20° and 50° in the uncorrelated disorientation distribution map under relatively large strains, showing the dislocation multiplication and transformation trend from low angle grain boundaries to high angle grain boundaries.
