The deformation behaviour of the Bi-2223 ceramic core in an Ag/Bi-2223 composite, which is crucial for obtaining a high critical current density, has been investigated for the Ag/Bi-2223 composites where the Bi-2223 filament was located at different positions in the silver matrix. For the cores located at the mid-plane of the tape, the thickness strain and the lateral strain were large. For the cores located near the tape surface, the thickness strain and lateral strain were minimized. In a 19-filament Ag/Bi-2223 tape, the deformation state of the Bi-2223 core was less dependent on core position. It has been observed that the deformation behaviour of ceramic cores was very dependent on the core position in the silver matrix as well as the existence of the neighbouring ceramic cores. |
