摘要：
Monocore Bi-2223/Ag and Bi-2223/Ag-Mg tapes have been made by two axial (TAR) and eccentric rolling (ER). The pole figures gave a closer to reality distribution of c-axis orientation of crystallites for monocore Bi-2223 ceramics in comparison to standard evaluation by 'rocking curves'. Texturization of crystallites in the 'transverse' direction of the monocore Bi-2223 tape had a minor effect on the tape performance. For rolled tapes with relatively high aspect ratios (similar to20) the crystallites' texturization in the 'rolling' direction was better then that in the 'transverse' direction. SEM observations at the Bi-2223/Ag interface were not objective for the judging of texturization, since the supercurrents flow beneath that interface.
