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.

Titanium-Vanadium Binary Alloys

1983
Ti-V has played a dominant role in the early development of type-II superconductivity. Since the late 1950’s when the results of transition temperature measurements were first reported, Ti-V has been subjected to both critical field and critical current measurement. The alloy has been investigated in both bulk and thin-film form, in the non-equilibrium

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.

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 ...

Analysis of vanadium—titanium ores and alloys

Talanta, 1994
A 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.

Recycling of vanadium alloys in fusion reactors

Journal of Nuclear Materials, 2007
The 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.

EXPLORATION OF VANADIUM-BASE ALLOYS

1955
Abstract : This is the third annual report. The oxidation study on vanadium alloys has been further pursued and the conclusion has been reached that satisfactory oxidation resistance at elevated temperature of vanadium-base alloys cannot be rendered by alloying alone but possibly by electroplating. Major efforts have been directed toward evaluating the

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

Effect of oxygen in sodium on vanadium and vanadium alloys

Journal of the Less Common Metals, 1970
Abstract Vanadium-base alloys are being considered as potential fuel cladding materials for sodium-cooled fast-breeder reactors. The mechanical and corrosion properties of vanadium alloys in sodium are strongly affected by oxygen impurities in the sodium.
