Abstract
A method for forming improved superconducting composites having improved Jc values by assembling octagonal or curved octagonal elements which when assembled allow for formation of uniformly continuously spaced voids. The voids are then filled with a metal, alloy, intermetallic substance, or ceramic oxide. The assembly of the octagonal elements and the filling of the voids is performed in a metal can. Accordingly, the flexibility in design of the present invention allows control of the performance of the superconductor and is cost effective.
Claims20
A method for manufacture of superconductors comprising the steps of:
- assembling at least four octagonal or curved octagonal metal elements to allow for the formation of uniform continuously spaced voids;
- and
- filling the uniformly spaced voids with a substance selected from the group comprising a metal, alloy, intermetallic substance, and ceramic oxide.
A method of manufacture of superconductors having improved critical current density, comprising the steps of:
- integrating NbTi or Nb octagonal elements during assembly, the elements providing natural formation of uniform regularly spaced voids for practical incorporation of artificial pinning centers within the NbTi or Nb matrix, wherein the elements improve the efficacy of the artificial pinning centers.
The method of manufacture of superconductors as in claim 29, wherein the void is in the range from about 2% to about 40%.
