Abstract
A method of manufacturing superconducting wires based on MgBis described and includes the steps of: production of a cylindrical wire comprising an MgBcore surrounded by a metal covering, in which the core has a lattice structure formed by grains of the compound MgB; rolling of the wire to produce a conductor in tape form; and subsequent heat treatment by heating to a temperature of between 800° C. to 870° C. This last step helps to increase the connection between the MgBgrains whilst retaining the structural defects produced in the rolling step, thus producing a superconducting wire with greater current-transport capacity.
