MgB2cable made from two-axially rolled wires

Stabilized seven-core MgB 2 cable has been made from two-axially rolled single-core wires with a Ti/Cu sheath. It was shown that drawing deformation applied prior to braiding influences the core density and consequently also the transport current density, J c . A proper drawing deformation allows avoiding J c degradation, and cable critical current density 10 4 A cm −2 at 9.5 T and 10 5 A cm −2 at 4.5 T can be reached at 4.2 K.
