Y.Ba2Cu3O7, a high TC superconductor powder, was shock compacted and explosively welded inside a copper matrix using the explosive fabrication methods described by Murr, Hare and Eror. The shock compression fabrication technique provides the ability to process the superconductor powders into useable structures that will minimize environmental degradation and will not negatively affect the physical or mechanical properties. Additionally, the introduction of shock induced defects are known to increase solid-state reactivity in ceramic materials. For this reason, shock compression fabrication of the superconductor/copper system offers the possibility of enhancing the superconducting properties of the YBa2Cu3O7 powders.
