摘　　要：用ＸＲＤ和ＳＥＭ系统研究了用套管法制备的Ｂｉ系高温超导带材的不同加工工艺过程对其微观组织的影响。试验结果表明，加工过程的每一步工序从粉末制备到拉拔、轧制、冷压及热处理工艺都影响带材的微观组织和超导性能。因此，每一步工序都要进行严格控制优化。A study of the microstructure changes that occurred when BPSCCO tapes were processed by the powderintube method has been carried outTechnical study exhibited that every step of procedure,such as powder,drawing,rolling,annealing and pressing cycles had a great influence on microstructure of the tapesRepeated pressing improved the alignment and density and repeated annealing allowed more conversion of 2212 to 2223,therefore caused the superconducting properties of the tapes improved
