Abstract
The combination of mechanical work by powder-in-tube processing and melt growth of YBa2Cu3O7-δ was investigated. During the heat treatment of Ag-sheathed YBa2Cu3O7-δ wire above the melting point of Ag, the sheath was melted and removed from the superconducting wire, but a small portion of Ag infiltrated into the core. Mechanical working before the heat treatment is beneficial for improvingJ c. Heat treatments above 1015°C resulted in higherJ c values for drawn wires than the samples without mechanical working. A proper combination of mechanical working and melt growth appears very promising for making high-J c wire with good strength.
