摘　　要：对 Bi系超导体热处理前后的轧制试样的高温超导相组成进行了分析。结果表明 ,经过轧制和热处理后 ,超导体的高温超导相组成发生了变化 ,其中 1 1 0 K相含量大大提高。热处理工艺所具有的较高的保温温度以及轧制工艺引起的超导晶粒的碎化是 1 1 0 K相含量提高的主要原因。WT5”,6BZ]In this paper, the constituents of high temperature superconducting phases in Bi based superconductor were analyzed. The results indicated the percentage of 110K phase increased greatly after rolling and heat treatment due to the higher temperature treatment and the fragmentation of superconducting grains during rolling.
