The work carried out: Defined methods, techniques and equipment and studies HCS in the following areas: - Study the thermodynamic and kinetic conditions of phase redistribution of nitrogen and vanadium in austenite and ferrite phase by chemical analysis; - Research dilatometer, metallographic methods and dyurometrical temperature and kinetic parameters and polymorphic phase transformations, including eutectial transformation; - Metallography, electron raster, atomic force microscopy, X-ray and X-ray structural analysis phase, including high temperature. Performed on research showed that the level of fatigue endurance HCS under cyclic exposure parameters defined initial pearlitic structure, and martensitic steels beynitnyh, their transformation and degradation in power and thermal effects. The possibility of a significant increase in fatigue endurance HCS by their nitrogen alloying and vanadium, which provides initial dispersion of steel structures - pearlite, bainite, martensite, their stability during heat treatment and under cyclic force and thermal stress, improve value properties of strength, ductility and 'viscosity nitride dispersion strengthening. In terms of applied research ensures the possibility of creating a future for transport and other engineering new brands HCS while increased 2-3 times the level of mechanical properties, fatigue endurance and durability.
