Abstract

The bending strains of Bi2223 filaments in Ag-sheathed superconducting composite tapes at the Bi2223/Ag sheath boundary have been evaluated by X-ray diffraction utilizing synchrotron radiation at room temperature. The strain in the Bi2223 filaments was found to be asymmetric between the sides under tension and compression, suggesting that the fracture strain is also asymmetric between tension and compression. The outermost part of the Bi2223 filaments is at the multiple fracture stage in the tension side.
