전열처리 조건에 따른 Bi-2223 초전도 선재에서의 특성 변화
Superconducting properties of Bi-2223 tapes with various pre-annealing conditions
초록
A lot of efforts have been focused on the optimization of PIT parameters for Bi-2223/Ag wire. Bi-2223 superconducting wires with 55 filaments were fabricated by stacking, drawing process. Before rolling process, round wires were pre -annealed at 760 - 820
