Description

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 (∼ 20) 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
