Aspects of forming metal-clad melt-processed Y-Ba-Cu-O tapes

The authors describe the manufacture of a tape of Y-Ba-Cu-O up to 25-cm long in nickel cladding using partial-melt processing. Magnetic and transport current measurements of the tapes were performed. Transport critical currents at 4.2 K of greater than 600 A have routinely been carried by these tape...

Description
Summary:The authors describe the manufacture of a tape of Y-Ba-Cu-O up to 25-cm long in nickel cladding using partial-melt processing. Magnetic and transport current measurements of the tapes were performed. Transport critical currents at 4.2 K of greater than 600 A have routinely been carried by these tapes. Magnetization measurements indicate that these high currents can be maintained up to 40 K. Aspects of selecting a criterion for establishing the transport critical current are discussed as they relate to applications.
