Microstructure and critical current densities of MgB/sub 2//Cu wires


Cu sheathed MgB/sub 2/ wires with a diameter of 2.50 mm and 0.93 mm have been fabricated by the In-Situ Powder-in-Tube PIT method. We have studied three subjects; the morphology of the wire core affected by the fabrication process of cold rolling, compounds in the core produced by the heat-treatment and effect of the microstructure on critical current… (More)
