摘要：
Sinter forging has been employed to improve critical current density of Bi-2223 bulks. After that, optimal post annealing is also very important to get good performance. Different annealing schedules have been used to produce Bi-2223 sinter-forged bulks in different atmospheres. In this paper, Bi-2223 long bulks were prepared by a combination of cold isostatic pressing (CIP) and sinter-forging techniques. The samples were undergone deformation rates from 50 to 90% totally. The effect of post annealing in atmosphere of 7.5% O2/N2 on critical current density Jc for such (Bi, Pb)2Sr2Ca2Cu3Oy long bulks was investigated. Their microstructure features and phase changes were also studied.
