Article Preview

The critical current versus tensile strain characteristics of mono- and multi-filament Bi-2223 tapes with Ag and AgMn and AgMg sheath has been studied. The strain tolerance ε0.9 of naked mono- and 37-filament Bi-2223 tapes were 0.13% and 0.20%, respectively. Ag sheath increased the strain tolerance ε0.9 of critical current by 0.08% and 0.16% for mono-filament and 37-filament Bi-2223/Ag tapes. The ε0.9 of Bi-2223 with Ag and AgMn and AgMg sheath increased with filament number. AgMn and AgMg sheath, increasing ε0.9 of Bi-2223 tapes by 0.07-0.09%, are effective to improve strain tolerance of critical current for multifilamentary Bi-2223 tapes.
