| 摘要 |
A method of preparing an Ag alloy/ceramic superconducting tape comprising a putting of a precursor powder into Ag or Ag alloyed tube to form a bar, drawing the bar into a wire of a predetermined diameter, cutting and bundling the wire to form a multifilament bar with an outer Ag or Ag alloyed tube (3) and putting the resultant bar into an additional tube (4) of e.g. Cu, Cu alloy, Al or steel. The multifilament bar is deformed by drawing, groove rolling or extrusion to form a wire, and the wire is thereafter rolled into a tape. The outer metal sheath will be removed either chemically or mechanically before heat treatment.
