Hydrogen trapping in niobium-vanadium alloys [PDF]

open access: yesJournal of Physics F: Metal Physics, 1986
The authors have measured the localised vibrational modes of hydrogen in a Nd0.93V0.07 alloy. As one cools the sample for the first time to 10K one observes that hydrogen is trapped at octahedral sites associated with two substitutional vanadium atoms. The trap energy is small (10-20 meV) and less than the precipitation enthalpy.

High thermoelectric figure of merit by resonant dopant in half-Heusler alloys

open access: yesAIP Advances, 2017
Half-Heusler alloys have been one of the benchmark high temperature thermoelectric materials owing to their thermal stability and promising figure of merit ZT. Simonson et al. early showed that small amounts of vanadium doped in Hf0.75Zr0.25NiSn enhanced

Processes, microstructure and properties of vanadium microalloyed steels [PDF]

open access: yes, 2009
Vanadium as an important alloying element in steels was initially associated with the properties achieved following tempering. Interest in the microstructure was stimulated by the advent of transmission electron microscopes with a resolution of ~1nm ...

Charge Redistribution and Phonon Entropy of Vanadium Alloys [PDF]

open access: yes, 2006
The effects of alloying on the lattice dynamics of vanadium were investigated using inelastic neutron scattering. Phonon densities of states were obtained for bcc solid solutions of V with 3d, 4d, and 5d transition metal solutes, from which vibrational ...

Replacement of Vanadium by Ferrovanadium in a Ti-Based Body Centred Cubic (BCC) Alloy: Towards a Low-Cost Hydrogen Storage Material

open access: yesApplied Sciences, 2018
We report here the effect on hydrogen sorption behavior of replacing vanadium by ferrovanadium (FeV) in Ti-V-Cr Body Centred Cubic (BCC) solid solution alloys. The compositions studied were Ti1.56V0.36Cr1.08 and Ti1.26V0.63Cr1.11. Both of the alloys were

Deuterium permeation through the low-activated V–4Cr–4Ti alloy under plasma irradiation

open access: yesNuclear Materials and Energy, 2020
Vanadium-based alloys are considered as candidate structural materials for nuclear fusion and fast nuclear reactors. Some properties of vanadium alloys are especially advantageous for nuclear fusion facilities, namely, a fast decay of induced activity ...

VANADIUM-CHROMIUM ALLOY SYSTEM [PDF]

open access: yes, 1959
On the basis of data obtained from melting point determinations, microscopic examination, and x-ray investigations, a phase diagram is proposed for the V-Cr alloy system The system forms a complete series of solid solutions with a minimum occurring in the solidus at 1750 deg C and approximately 70 wt.% Cr.

Effect of Microstructure of Fe-C-V Alloys on Selected Functional Properties

open access: yesArchives of Foundry Engineering, 2014
The cast alloys crystallizing in Fe-C-V system are classified as white cast iron, because all the carbon is bound in vanadium carbides. High vanadium cast iron has a very high abrasion resistance due to hard VC vanadium carbides.

Dispersion strengthening in vanadium microalloyed steels processed by simulated thin slab casting and direct charging: Part I - Processing parameters, mechanical properties and microstructure [PDF]

open access: yes, 2007
A study simulating thin slab continuous casting followed by direct charging into an equalisation furnace has been undertaken based on six low carbon (0.06wt-%) vanadium microalloyed steels.

Electron-phonon interactions and high-temperature thermodynamics of vanadium and its alloys [PDF]

open access: yes, 2008
Inelastic neutron scattering was used to measure the phonon densities of states (DOSs) for pure V and solid solutions of V with 6 to 7at% of Co, Nb, and Pt, at temperatures from 10 K to 1323 K.
