DYNAMIC HIGH PRESSURE PRODUCTION OF SUPERCONDUCTIVE MATERIAL AND PERMANENT MAGNET MATERIAL

摘要

Shock wave formation of thin layers of materials with improved superconducting and permanent magnetic properties and improved microstructures. The material fabrication system includes a sandwiched structure including a powder material placed between two solid members to enable explosive shock consolidation. The two solid members are precooled to about 80 DEG -100 DEG K. to reduce the residual temperatures attained as a result of the shock wave treatment, and thereby increase the quench rate of the consolidated powder.
