Abstract

Top-seeded power melting process (TSPMP) is an effective melting processing technique for the preparation of high J_c bulk YBCO. The directional solidification is also a quite common technique used to produce well-oriented cylinder grains. The two processes were combined (named Directional Top-seeded power melting process DTSPMP) to fabricate good YBCO bulk with well-oriented domains. The seed transferring effect and the change of the solute concentration in liquid were analyzed. The effects of temperature gradient (TG) on the orientation and continuous growth of large grains were also investigated. As a consequence of studying the microstructure dependence on pulling rate through canning electric microscopy(SEM), it was found that the large domains can be obtained and the fine 211 particles were entrapped at a slower pulling rate.
