Radiation effects in vanadium and vanad ium-base alloys
International Materials Reviews, 1980AbstractA comprehensive review is presented of the effects of high-energy neutron and ion irradiation on the mechanical properties, dimensional stability, and microstructural response of unalloyed vanadium and vanadium-base alloys. Only bulk radration effects are conside red; the response of the surface to ionizing radiation is not discussed.

Analysis of vanadium—titanium ores and alloys
Talanta, 1994A new spectrophotometric method for determining titanium in vanadium-titanium ore with 2,2'-biquinoxalyl was developed. The analytical procedure to dissolve samples and separate titanium from vanadium and tin was elaborated as well. Furthermore, vanadium and iron were determined in the ore investigated.

Blanket neutronics of Li/vanadium-alloy and Flibe/vanadium-alloy systems for FFHR
Fusion Engineering and Design, 2006Abstract Neutronics calculations were carried out to characterize self-cooled Li and Flibe blankets with vanadium alloy (V–4Cr–4Ti) structure, as advanced options for the Force Free Helical Reactor (FFHR-2). In the present paper, the parameter dependence of Tritium Breeding Ratio (TBR) and neutron shield performance was examined for a Li blanket ...

Mechanical properties of vanadium-alloyed copper and nickel-vanadium alloys at elevated temperatures
Metal Science and Heat Treatment of Metals, 19611. Vanadium is useful deoxidizing and alloying addition to copper and nickel; small additions (up to 0.4% in copper and up to 1% in nickel) improve the mechanical properties of the alloys while reducing the effect of temperature on static tensile strength. 2. Addition of vanadium to copper eleminates the brittle range at 500°C.

Recycling of vanadium alloys in fusion reactors
Journal of Nuclear Materials, 2007The feasibility of reprocessing a vanadium alloy after its use as a structural material in a fusion reactor, in order to enable its subsequent hands-on recycling within the nuclear industry, has been determined. For less neutron-exposed components, clearance of materials has also been considered.

Vanadium self-diffusion in pure vanadium and in dilute vanadium-iron and vanadium-tantalum alloys
Philosophical Magazine Part B, 1983Abstract Measurements of vanadium self-diffusion have been made over the temperature range 1050–1874°C. The solute enhancement factor b for vanadium self-diffusion has also been measured in dilute vanadium-iron and vanadium-tantalum alloys. These results, together with the authors' previously published results on iron impurity diffusion in vanadium ...

Gas-metal reactions in vanadium and vanadium-base alloys
International Metals Reviews, 1980AbstractThe interaction of unalloyed vanadium with carbon, oxygen, nitrogen, and hydrogen and the effects of these elements on the mechanical behaviour of vanadium and vanadium alloys are reviewed. Hydrogen, nitrogen, and oxygen exhibit high solid solubility (≥2 at.-% at 500°C) while carbon solubility in vanadium is less than O.

Superconductivity of vanadium and vanadium-titanium alloys at high pressure
JETP Letters, 2009The effect of pressure on the superconducting transition temperature T c of vanadium and V94Ti6, V85Ti15, V67Ti33, and V48Ti52 (at %) bcc alloys has been studied. It has been found that the T c(P) dependence of pure vanadium is close to linear in the pressure ranges 0–14 and 23–32 GPa, whereas dT

Consolidation and fabrication of vanadium and vanadium-base alloys
International Metals Reviews, 1980AbstractA review is presented on the current state of technology on the consolidation and fabrication of vanadium and vanadium alloys. Commercial quantities of pure vanadium metal (99.9+%) have been produced by the metallothermic reduction of V2O5 followed by electron-beam refining.
