Abstract
Axisymmetric explosive powder compaction and subsequent direct extrusi on are employed to fabricate a multi-layered metal/high-T-c ceramic ro d consisting of a silver mandrel, a potassium doped YBa2Cu3O7 core and a steel sheath. Experimental investigations regarding the 'soundness' and the superconducting properties of the component at the various st ages of the fabrication are reported. Microstructural/crystallographic changes, macro- and micro-defects of the 'green' compacted billet and the extruded rod are also indicated and discussed.
