摘要： A new heat treatment for Internal-Tin Nb3Sn strands is described. The heat treatment uses Nausite membranes to decrease the volume fraction of the η phase and therefore minimize its liquefaction—ultimately resulting in better connected Nb3Sn. The heat treatment requires only one stage aside from the final Nb3Sn reaction stage. This heat treatment enables an increase in critical current density (at 16 T) of 28%.

摘要： A method of producing a Nb3Sn superconducting wire rod includes forming a wire rod comprising Nb, Sn and Cu, and having a mole ratio of the Sn expressed as ax+b(1−x), where 0.25≦x≦0.8, 0.3≦a≦0.4 and 0.02≦b≦0.1, and x and 1−x are prescribed as a mole ratio of the Nb and a mole ratio of the Cu, respectively, to a total of a mole number of the Nb and a mole number of the Cu, and heating the wire rod to produce Nb3Sn from the Sn and the Nb. By the heating of the wire rod, a Cu—Sn alloy is produced from the Sn and the Cu, concurrently with the Nb3Sn produced from the Sn and the Nb.

摘要： A method for producing a superconductive wire, whereby an elongated intermediate element is formed out of an initial element in a deformation step and whereby the superconductive filaments are formed by a final reaction heat treatment, is characterized in that prior to the final reaction heat treatment the filaments in the intermediate element are densified in one or more high pressure densification steps following up the deformation step, said densification steps comprising a simultaneous action of at least four hard surfaces perpendicular to the axis of the elongated intermediate element, building up high pressure P≧100 MPa on a part of the intermediate element having an axial length L. This leads to a substantial increase of the critical current density Jc, whereby the anisotropy factor F is be almost not affected thus enabling production of almost isotropic wires or tapes.
