摘要

铜镍合金基带是制备双轴织构钇钡铜氧(YBCO)涂层超导体的优良合金基带之一。采用轧制辅助双轴织构基带技术(RABiTS)制备无磁性的CuNi金属合金基带。采用X射线衍射技术(XRD)及背散衍射技术(EBSD)对CuNi合金基带再结晶热处理后的织构表征分析发现,热处理工艺是影响合金基带再结晶晶粒取向的重要因素之一。结果表明,对CuNi合金基带进行950℃下保温60min的最佳热处理工艺后,CuNi合金基带表面形成了锐利的立方织构,其立方织构的含量高达97%(≤10o)。
        Cu-Ni is one of good materials as a substrate for producing biaxially textured YBCO coating conductors.The non-magnetic CuNi alloy substrate was prepared by rolling assisted biaxially textured substrates (RABiTS) technology.The orientation as a function of annealing temperatures for the as-obtained CuNi substrate was characterized by XRD and EBSD.The results show that the heat treatment process is an important factor for the texture transition in CuNi alloy substrate.The percentage of the cube texture in CuNi alloy substrate obtained by the optimized heat treatment process is as high as 97.0% within a tolerance angle smaller than 10o.The optimized heat treatment process is holding the tape at 950oC for 60 min.
