Abstrakt: Studies of the structure and properties of high-nitrogen corrosion-resistant aging nonmagnetic vanadium steels have been analyzed. The hardening of these steels by fine vanadium nitride and carbonitride particles is considered. The mechanisms of the discontinuous decomposition of austenite supersaturated by nitrogen upon heat treatment are described. Methods for the removal of the negative effect of the discontinuous decomposition on the mechanical properties of high-nitrogen steels have been found. Steels with an overequilibrium nitrogen content are shown to exhibit superplasticity. The dependences of the microstructure and properties of high-nitrogen vanadium austenitic steels on their alloying and the conditions of thermal and thermoplastic treatments are considered.
