Abstract

The effects of axial tensile and bending strains on the critical current of Ag and AgMn/Bi-based tapes produced by the powder-in-tube method have been studied at 77 K. The observed degradation of critical current due to tensile strain effects is irreversible. AgMn sheath and multifilament are beneficial to improve the tensile and bending strain tolerance of Bi-2223 superconducting tapes. In the case of Ag/Bi-based tapes, the ε_irr ≈ 0.15%, while that of AgMn/Bi-based tapes is 0.34%. The larger tensile and bending strain tolerance of AgMn/Bi-2223 superconducting tape may result from better mechanical properties.
