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.

JOM, 1963
The potential of V alloys for applications above 2000 deg F is described. Mechanical properties are tabulated and reviewed, with major emphasis on the V-Nb alloys. Evaluations of fabricability are considered, and investigations of several oxidation-protection systems, particularly packsiliconizing treatment are detailed. (auth) nium dioxide. (auth)

Thermotransport and diffusion of carbon in vanadium and vanadium-titanium alloys
Journal of the Less Common Metals, 1986Abstract Studies concerning the thermotransport and diffusion of carbon in vanadium and V-Ti alloys were made using a radioactive tracer technique. Thermotransport of carbon is towards the hotter region for all compositions, which corresponds to a negative heat of transport. Its magnitude decreases monotonically with increasing titanium content from −

Calorimetric Studies of the Behavior of Hydrogen in Vanadium and Vanadium Alloys
Journal of the Physical Society of Japan, 1985Calorimetric measurements have been made on vanadium hydride (and deute-ride) to investigate the origin of excess specific heat due to H(D) atoms and the mechanism of phase transitions. The specific heat in the α phase was found to increase linearly with H(D) concentration at the rate of 2.0±0.1 k B /H atom and 2.4±0.1 k B /D atom at 240°C, nearly ...

The phase diagram shown in Fig. 100 is due to [1]. A diagram covering the whole composition range was produced at about the same time by [2]. Although there is good agreement in some respects, there are also considerable differences, especially with regard to melting points, and in view of the authors’ own comments on the small number of samples ...

Application of vanadium and vanadium alloys to a fusion reactor blanket
Journal of Nuclear Materials, 1984Abstract Vanadium and vanadium alloys are of interest in fusion reactor blanket applications due to their low induced radioactivity and outstanding elevated temperature mechanical properties during neutron irradiation. The major limitation to the use of vanadium is its sensitivity to oxygen impurities in the blanket environment, leading to oxygen ...
