| Popis: | Axisymmetric explosive compaction with a shock-wave pressure of 2 GPa was used to obtain low-resistance Ag/YBCO (YBa2Cu3O7−x) contacts. Measurements were made of compressive strength at 300 K and microhardness and electrical resistivity within the temperature interval 300–77 K for annealed specimens of Ag/YBCO. Ultimate compressive strength was 0.12 GPa. The microhardness of the ceramic near the Ag/YBCO interface was 3.1 GPa. Contact resistance at the temperature of liquid nitrogen |
