Critical current densities at 77 K and 4.2 K of Bi(2223) tapes prepared by cold and hot deformation

Abstract

Monofilamentary Bi(2223) tapes have been prepared by the Powder-In-Tube technique using various alternatives for the final thermomechanical processing. In particular, both cold and hot deformation processes were investigated and their critical current densities at 77 K and 4.2 K were measured. For long cold rolled Bi(2223) tapes, transport j/sub c/ values… (More)
