A method of manufacturing superconducting wires based on MgB2 is described and includes the steps of : production of a cylindrical wire comprising an MgB2 core surrounded by a metal covering, in which the core has a lattice structure formed by grains of the compound MgB2; 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 MgB2 grains whilst retaining the structural defects produced in the rolling step, thus producing a superconducting wire with greater current-transport capacity.
L'invention concerne un procédé de fabrication de fils supraconducteurs à base de MgB¿2?. Ce procédé comprend les étapes consistant à produire un fil cylindrique comprenant une âme de MgB¿2? entourée d'un revêtement métallique, cette âme possédant une structure du réseau cristallin formée de grains du composé MgB¿2?, à laminer ce fil afin de produire un conducteur en forme de bande, puis à traiter thermiquement ce conducteur en le chauffant à une température comprise entre 800 et 870 ·C. Cette dernière étape permet d'augmenter la liaison entre les grains de MgB¿2? tout en retenant les défauts structurels produits lors de l'étape de laminage, ce qui permet de produire un fil supraconducteur possédant une plus grande capacité de transmission de courant.
