The texture evolution of copper tube manufactured by floating plug drawing process was investigated by Electron Backscatter Diffraction techniques and Visco-Plastic Self-consistent (VPSC) modelling method. The results obtained from experimentation indicate that the initial textures of copper tube transformed sharply after the first pass of the drawing process, and the final textures in the tube consist of Goss {110} <001> and P {110} <111> components. The VPSC model was established in order to study the texture transformation and the activity of slip systems of the tube during the drawing process. Two types of transformation paths were proposed to explain the mechanism of the texture evolution, which has a good agreement with the VPSC simulation results.

采用电子背散射衍射技术和粘塑性自洽（VPSC）建模方法研究了浮塞拉拔工艺制造的铜管的织构演变。实验结果表明，经过第一道拉拔工艺后，铜管的初始织构急剧变化，管内最终织构由高斯{110}<001>和P{110}<111>成分组成。VPSC模型的建立是为了研究拉拔过程中管子的织构转换和滑移系统的活动。提出了两种类型的转换路径来解释纹理演化的机制，与VPSC模拟结果具有很好的一致性。
