Research Abstract |
The three-dimensional penetration method combined with semi-solid casting was used to fabricate superconducting wires from metal-powder composite superconducting materials of MgB2 with aluminum, magnesium, and zinc alloys, having lightweight and good formability properties.Measured electrical resistivity showed a clear signal of superconducting transition between 25 and 39 Kfor all the samples cut out from the composites. A magnetic hysteresis loop indicated that simultaneously doped Al and Zn to magnesium host-matrix (MgB2/Mg-Al-Zn) enhanced the critical current density. A superconducting wire of a diameter of 1.0 mm was successfully extruded from the composited billet of MgB2/Al.
