摘要

Powder-in-tube mono- and multifilamentary tapes with sheaths of Ag, AgCu0.02, Ag(AgCu0.02), AgAk(0.25), Ag(AgAl0.25), AgNi0.25Mg0.25, AgTi0.25Mg0.25, and AgTi0.25 alloys have been fabricated and their physico-chemical properties and effect on the phase formation of Bi-2223 determined. Alloying was found to have a significant effect on phase formation of the Bi-2223 phase formation linked to the alloying elements reactivity to oxygen Cu < Ni < Al < Mg < Ti. Multifilamentary tapes, composed of an inner Ag sheath and an outer Ag alloy sheath showed no such effects. The resistivity and mechanical properties of the various Ag alloys used as sheathing materials are also reported on and their possible use in improving the performance of PIT tapes.
