The influence of pressure (isostatic - up to 16 МPа, hot pressure - 30 МPа, quasi-isostatic 0,5-8 GPа) and temperature (600-1800 оС) on structure and properties of above mentioned materials was studied. For the first time was shown the possibility to manufacture the single-phase nonporous MAX materials (Ti3AlC2 and Ti2Al1.1(CxN(1-x)) solid solutions) by thermobaric consolidation at 2 GPа, 1300-1400 оС). The oxidation-resistant (up to 1350 оС) material with high level of damping properties based on Ti3AlC2 phase has been developed. The superconducting nanostructural YBaCuO-based ceramic material with critical current density 100 kА/cm2 has been created. The material is produced by oxygenation under the increased pressure (<10 МPа) and temperature 700-800 оС and is characterized by high twin density being free of dislocations and stacking faults. The developed MgB2-based high-dense composite materials reveal the high level of superconducting properties: critical current density 106 A/cm2 in 1T magnetic field at 20 K, upper critical magnetic field (Bc2) and field of irreversibility (Birr) run to 15 T at 22 K and 18,4 K, respectively. The critical magnetic field at 0 К, Bc2(0 K), estimated by approximation is 40 T. The superconducting properties have been defined in MgB12-based materials synthesized under high pressure.
