【摘要】：采用压延辅助双轴织构基板制备路线成功轧制出长度大于100 m、厚度约为66μm的Ni-5at%W(Ni5W)合金长带,从中截取10 m长带在自制的卷到卷热处理系统中进行再结晶动态退火处理。XRD织构分析显示,整条长带退火前的轧制织构含量平均值为63.8%(≤10°),动态退火长带面内和面外织构的半高宽平均值分别为7.2°和6.1°。EBSD分析发现,基带立方织构含量为98.7%(≤10°),小角晶界含量为87.7%(≤10°)。长带轧制过程中变更轧机时增加首道次压下量可以有效改善轧制过程中带材断裂的情况。此工艺可以制备出符合YBCO超导层需求的、具有高立方织构含量和均匀性的Ni5W合金长带。
