Superconductivity of vanadium and vanadium-titanium alloys at high pressure

JETP Letters, 2009
The 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, 1980
AbstractA 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.

Vanadium Alloys in Aerospace

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, 1986
Abstract 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, 1985
Calorimetric 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 ...

Alloys with Vanadium

1991
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, 1984
Abstract 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 ...

Alloying and impurity effects in vanadium-base alloys

Journal of Nuclear Materials, 1986
Abstract Vanadium-base alloys offer a number of significant advantages over other alloy systems for fusion reactor structural applications. However, the properties and performance of vanadium are strongly influenced by the choice of alloying additions and the presence of impurity elements, and these effects are reviewed in this paper.

Investigation on mechanical alloying process for vanadium alloys

Journal of Nuclear Materials, 2013
Abstract Mechanical alloying (MA) is an efficient approach for fabricating particle-dispersion alloys, and has recently been introduced to strengthen structural materials including vanadium alloys for fusion application. Dissolution behavior of the alloying elements is a key issue for optimizing MA in fabricating particle-dispersion vanadium alloys ...
