The electrodeposition process of vanadium from LiCl-KCl base electrolytes was investigated by means of cyclic voltammetry, galvanostatic electrolyses and micro analytical analysis of the deposits. It is demonstrated that the valence state of the vanadium ions has a critical influence on the feasibility of performing a reproducible and stable coating process aiming to obtain compact vanadium films. When the electrolyte contained predominantly trivalent vanadium ions, the process was unstable and the deposit consisted of dendrites. In contrast, making use of a comproportionation reaction of metallic vanadium and VCl 3 to divalent vanadium ions led to a stable deposition behaviour and allowed to obtain thick deposits with high current efficiencies. The disadvantageous behaviour of melts with mostly trivalent ions is explained by the fact that deposition is interfered by the reduction of trivalent to divalent ions under limiting current conditions.

“…Low-activated vanadium alloys of V-Ti-Cr system (V-4Ti-4Cr is the best reference alloy) as the structural materials for cores of fusion and fission (fast) nuclear reactors are considered [1][2][3][4]. New compositions of vanadium low-activated alloys of V-Me(Cr, W)-Zr-С system demonstrate good prospects [5].…”

a b s t r a c tFormation of regularities of the nanometric oxide precipitates and defect microstructure in vanadium-based low activation alloys V-Cr-Zr-(C,N,O) and V-Cr-W-Zr-(C,N,O) as a function of the regimes of their thermochemical treatment was investigated. Several methods of internal oxidation which provide formation of the nanosized ZrO 2 particles of controllable dispersion, ensure the nanometric size of the heterophase structure to be maintained up to the temperatures as high as 1300-1400°С, and allow the recrystallization temperature to be increased up to ≥1400°С were proposed. Formation of such microstructure contributes to dispersionand substructural hardening and results in more than twofold increase in the yield stress of these alloys both at room and elevated (800°С) temperatures, compared to the conventional thermo-mechanical treatment.

“…Vanadium alloys are one of the prospective structural materials in fusion reactors [1][2][3][4][5][6][7][8][9][10][11][12][13]. Vanadium has relatively low activation properties [1], high thermal stress factors [2] and relatively good radiation resistance with moderate swelling properties [5,8].…”

“…Vanadium has relatively low activation properties [1], high thermal stress factors [2] and relatively good radiation resistance with moderate swelling properties [5,8]. Embrittlement by transmuted helium [7] and enhanced creep induced by neutron irradiation [9][10][11] are, however, issues in V base alloys. Considerable efforts have been made to improve high temperature strength, ductility at low temperatures, thermal or irradiation induced creep resistance and degradation under irradiation environment [9,12,14].…”

The microstructure and the strength of high pressure torsion processed V-5Cr-5Ti alloy are investigated by X-ray line profile analysis and microhardness testing. High pressure torsion has been applied at 4 and 8 GPa with 0.25, 0.5, 1, 2, 4 and 8 rotations. The X-ray beam of the high angular resolution diffractometer, dedicated for line profile analysis, has a footprint of about 200 m1.5 mm on the specimen. The diffraction patterns have been measured in the center, at half radius and close to the edge of the specimens. This technique has provided a large number of data of the microstructure and hardness as a function of strain up to about 300. The dislocation density determined by X-ray line broadening is correlated and discussed in terms of the strength of the alloy using the Taylor equation.
