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)

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 ...

Vanadium-Zirconium Alloy System
JOM, 1955The equilibria in the V-Zr alloy system were investigated by solidus temperature determinations, thermal analysis, dilatometry, electrical resistance measurements, microscopic examination, and X-ray diffraction analysis. There is a eutectic reaction at 1230°C between a compound, V2Zr, and a solid solution containing 10 pet V in β zirconium.

Microstructure of Vanadium-Oxygen Alloys
Proceedings, annual meeting, Electron Microscopy Society of America, 1981The present study is a continuation of our investigation on in situ oxidation of vanadium and vanadium-titanium alloys. Vanadium is a reactive metal and forms a large number of oxides during high-temperature exposure to oxygen. The microstructure of the oxides formed during the first stages of oxidation and the transformations between oxide phases are ...

Interdiffusion in niobium-vanadium alloys
Journal of the Less Common Metals, 1965Abstract A determination of the variation of interdiffusion coefficient with composition for Nb-V alloys has been made for diffusion temperatures of 1404°, 1505°, 1630° and 1750°C. Three types of doubly infinite couples were employed: Nb/V, Nb/alloy and V/alloy, where the alloy was 50 at.% Nb.

Alloying and impurity effects in vanadium-base alloys
Journal of Nuclear Materials, 1986Abstract 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
1983Ti-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, 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.

Investigation on mechanical alloying process for vanadium alloys
Journal of Nuclear Materials, 2013Abstract 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, 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.
