摘要：

A liquid-phase processing method has been developed to manufacture bulk YBa2Cu3Ox/Ag superconducting composites with large current carrying capacity and enhanced mechanical properties. Transport critical current density of 10,000 A/cm2is obtained in nominal 15 wt.% Ag composite using continuous direct current at 77 K and zero applied field. Using a pulsed current of 2 ms duration, a critical current density of 22,000 A/cm2is obtained. This composite has a Young's modulus of 100 GPa and a fracture stress of 70 MPa, which are infstantially higher than those of sintered 1-2-3 superconductor. © 1990 IOP Publishing Ltd.
