Superconductivity of Vanadium Alloys

Journal of the Physical Society of Japan, 1985
The effects of iron impurities up to 8 at% and of tantalum ones up to 10 at% on superconductivity is studied. The concentration dependence of various superconducting properties such as T c and d H c2 /d T | T c changes at a few at% of solute concentration.

Columbium-vanadium alloy system

JOM, 1954
On the basis of microscopic studies, melting-point observations, and X-ray analyses, a phase diagram is proposed for the Cb-V system. A complete series of solid solutions is formed with a minimum in the solidus at 1810°C near 35 wt pct Cb. No compounds or intermediate phases were found in the system above 650°C.

Sputtered clusters from niobium-vanadium alloys

Applications of Surface Science, 1982
Abstract A series of NbV alloys have been irradiated by 6 keV argon ions. Homonuclear and heteronuclear clusters emitted from these alloys have been studied by means of post-ionization and/or secondary ion mass spectrometry. The intensity of clusters of atomic masses up to approximately 300 amu was related to the concentrations of Nb and V in the ...

Mechanical properties of vanadium and vanadium-base alloys

International Metals Reviews, 1980
Abstract A comprehensive compilation and review is presented of the information available on the mechanical properties of vanadium and vanadium-base alloys. The total mechanicalproperty data base, as available in both the open and ‘closed’ literature (e.g.

Radiation effects in vanadium and vanad ium-base alloys

International Materials Reviews, 1980
AbstractA 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.

Blanket neutronics of Li/vanadium-alloy and Flibe/vanadium-alloy systems for FFHR

Fusion Engineering and Design, 2006
Abstract 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 ...

Gas-metal reactions in vanadium and vanadium-base alloys

International Metals Reviews, 1980
AbstractThe 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.

Mechanical properties of vanadium-alloyed copper and nickel-vanadium alloys at elevated temperatures

Metal Science and Heat Treatment of Metals, 1961
1. 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.

Vanadium self-diffusion in pure vanadium and in dilute vanadium-iron and vanadium-tantalum alloys

Philosophical Magazine Part B, 1983
Abstract 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 ...

IMPROVED VANADIUM-BASE ALLOYS

1961
Abstract : Alloys based on V-5w/oTi-20w/oCb and V-60w/oCb were found to exhibit excellent fabricability and weldability with good retention of strength to at least 2200 deg F. Ultimate tensile strength values of materials at the 60w/o columbuim level measured under He were above 60,000 psi at 2000 deg F and up to 44,400 psi at 2200 deg F; the strongest
