中文摘要：

Cu是制备双轴织构YBCO高温超导涂层的优良基带材料之一，立方织构的铜带可以提供良好的外延生长环境。文中采用轧制辅助双轴织构基带技术（RABiTS），研究了立方织构铜基带的制备工艺。将铜锭在初轧变形量达到88．4％后，进行400℃退火30min，再经二次轧制总变形量达到99．07％后，在氩气环境125—850℃之间不同温度下退火30min。用March—Dollase函数计算该系列样品的r值，其中850℃退火的样品具有最强的200择优取向，r值为0．25，用不完整极图对该样品的织构情况做进一步分析，用ODF函数定量计算了该样品立方织构的体积百分含量。该样品形成了较强的{001}〈100〉立方织构，体积百分含量为70．8％。

英文摘要：

Cu is one of good materials as a substrate for producing biaxially textured YBCO superconductor films, and the cubic texturing of Cu sheets can supply compatible environment for epitaxial growth. Using the rolling - assisted biaxially textured substrates （RABiTS） technique, the present work reported the preparation process for cubic texturing of Cu sheets. The copper ingot was wiled firstly to a tape with 88.4% total thickness reduction and annealed at 400℃ for 30min in argon. The annealed tape was further cold rolled to a tape with 99.07% total thickness reduction and annealed at a temperature from 125 to 850℃ for 30min in argon atmosphere. The March - Dollase coefficient value r was calculated for the samples of different secondary annealed temperature. The sample after annealing at 850℃ formed the best 200 preferred orientation, r was 0.25. Uncompleted pole figure was used to make a further analysis for the sample＇s texture, and orientation distribution function ODF was performed to calculated quantitative texture components. The sample exhibited sharp {001} 〈 100 〉 cubic texture, cubic texture fraction was 70.8%.
