    摘要: Lead based Type II superconducting alloys having high critical current densities are described. The alloys of the invention are characterized by having a matrix of lead and bismuth and/or indium and having a dispersion of particles of copper, tellurium, selenium, nickel, manganese, calcium, chromium, cerium, germanium or lanthanum or of compounds of these with the matrix constituents having an average particle size less than 2 preferably less than 0.5 microns. The alloys of the invention are preferably made by splat casting.

    摘要: A plurality of rods are assembled in a predetermined configuration to form a core which is surrounded by a molten matrix metal within a heated crucible. The temperature of the thusly charged crucible''s upper portion is maintained above the matrix metal''s melting point. In this respect, as the heat is applied to the top of the melt, the crucible is maintained in a hot environment while the bottom of the crucible is centrally chilled. In this manner the charge is solidified from the bottom toward the top so that the solidification progresses upwardly and outwardly in a conical pattern. After the controlled solidification is completed the casting is separated from the crucible to form a cored extrusion billet. In one embodiment the rods are separated from the casting and the resulting open holes are filled with superconductive material to form a composite superconductor extrusion billet. In another embodiment the rods themselves are made of a superconductive material so as to eliminate the step of separating the rods from the casting.
