摘要
利用X射线晶面衍射分析方法和扫描电镜观察手段,分析了Bi系超导带材在轧制前后以及热处理前后的晶粒取向性.实验结果表明,轧制工艺导致了有利于超导材料电学性能的晶粒取向性分布,超导晶粒的片平面即(001)晶面沿轧制平面作一致排列,这种取向性在热处理中得到了保留和加强.
X-ray diffraction experiment and SEM observation are used to investigate the effect of foiling and heat treatment on the grains alignment in Bi-Based tape superconductor, the results indicate that rolling can result in the (001) plane orientation alignment which improved the superconductor's electrical properties. This alignment is remained and enhanced during heat treatment.
