Results of scientific activity:
- Assembly of arc melting (VDP) “DUGA” is intended for remelting of consumed electrodes by electrical arc with power 300 kVt/5000 A and 60V in vacuum or in atmosphere of inert gases. Iron, nickel, vanadium and others also as alloys on their base may be remelted. Crystallization is performed in water cooled crystallizer. The assembly may produce ingots with mass up to 250 kg.;
- The method of control of gas impurities in zirconium alloys ingots on the stage of VDP remelting is developed. The proposed method guarantees the refining of zirconium alloy of gaseous impurities and provides uniformly low distribution of their residual content. This is achieved by the introduction of deoxidizer in the zone of melting with the use of local source of heat. The distinctions of melting such as considerable layer of liquid metal and presence of ionized active pair are used more completely in comparison with other processes of melting;
- It is revealed that micro impurities of rear-earth metals together with the use of dynamic action during the melt crystallization decreases the value of microchemical inhomogeneity of steels and zirconium alloys which allows the improvement of their mechanical characteristics;
- Analytical describing of metal joining in solid phase is performed which allows to form the necessary structures and properties of metals in the region of joining: increased strength, fatigue strength at high and low temperatures, corrosion resistance in aggressive media, corrosive-mechanical strength, serviceability under high thermal loads and effect of different irradiations. It is shown that the main mechanism responsible for materials welding in solid phase under rolling is production in crystal of torsion ductility and its fragmentation with production of joint disclinations. It is revealed that the main factor in radiation stability of glass-ceramic compositions is the optimal relation of initial crystalline grains and semi – amorphous base mass (1:3) under which radiation production of defects at different processes of grain amorphization and crystallization of the base mass reaches the minimum values.
- It is revealed that optimal composition of impurities and proportion of synthesis of ceramic products with increased radiation and corrosion resistance in condition of their operation including long-term containment of RAV in geological formation of similar composition on the base of investigation of the influence of impurities of oxide, fluoride and silicate composition to initial materials: absorbing carbides B4C(Cr2O3, NiO); structural – nitride β-Si3N4(MgO, CaF2), glass-ceramic compositional matrix for storage of RAV (with different content of natural rocks).
