摘要：

The synthesis of MgB2-based materials under high pressure gave the possibility to suppress the evaporation of magnesium and to obtain near theoretically dense nanograined structures with high superconducting, thermal conducting, and mechanical characteristics: critical current densities of 1.8-1.0x10(6) A/cm(2) in the self-field and 10(3) A/cm(2) in a magnetic field of 8 T at 20 K, 5-3x10(5) A/cm(2) in self-field at 30 K, the corresponding critical fields being H (c2)=15 T at 22 K and irreversible fields H (irr)=13 T at 20 K, and H (irr)=3.5 T at 30 K, thermal conduction of 53 +/- 2 W/(m.K), the Vickers hardness H (V) =10.12 +/- 0.2 GPa under a load of 148.8 N and the fracture toughness K (1C) =7.6 +/- 2.0 MPa.m(0.5) under the same load, the Young modulus E=213 GPa. Estimation of quenching current and AC losses allowed the conclusion that high-pressure-prepared materials are promising for application in transformer-type fault current limiters working at 20-30 K.
