Performance Of Oxide Dispersion Strengthened Superconductor Composites
Performance Of Oxide Dispersion Strengthened Superconductor Composites
US Patent:
6436875, Aug 20, 2002
Filed:
Mar 22, 2001
Appl. No.:
09/815063
Inventors:
Lawrence J. Masur - Needham MA
Donald R. Parker - Randolph MA
Eric R. Podtburg - Natick MA
Peter R. Roberts - Groton MA
Ronald D. Parrella - Shrewsbury MA

Assignee:
American Superconductor Corporation - Westborough MA
International Classification:
C04B 3564
US Classification:
505500, 505433, 505501, 505742, 29599
Abstract:
The invention features high performing composite superconducting oxide articles that can be produced from OPIT precursors substantially without poisoning the superconductor. In general, the superconducting oxide is substantially surrounded by a matrix material. The matrix material contains a first constraining material including a noble metal and a second metal. The second metal is a relatively reducing metal which lowers the overall oxygen activity of the matrix material and the article at a precursor process point prior to oxidation of the second metal. The second metal is substantially converted to a metal oxide dispersed in the matrix during or prior to a first phase conversion heat treatment but after formation of the composite, creating an ODS matrix.

Appl. No.:

Assignee:
American Superconductor Corporation - Westborough MA
International Classification:
H01B 1202
US Classification:
505231, 505236, 505237, 505431, 505704, 1741251, 29599, 428702, 428930
Abstract:
A multifilamentary superconductor composite having a high fill factor is formed from a plurality of stacked monofilament precursor elements, each of which includes a low density superconductor precursor monofilament. The precursor elements all have substantially the same dimensions and characteristics, and are stacked in a rectilinear configuration and consolidated to provide a multifilamentary precursor composite. The composite is thereafter thermomechanically processed to provide a superconductor composite in which each monofilament is less than about 50 microns thick.
