Interactions of molybdenum and vanadium with iron nanoparticles [PDF]

open access: yes, 2010
Molybdenum, vanadium and iron are important micro and macro nutrients, respectively, for all living organisms. Their cycles and budgets in the natural environment is affected by - and affects many different processes.

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 ...

Dispersion strengthening in vanadium microalloyed steels processed by simulated thin slab casting and direct charging. Part 2 - chemical characterisation of dispersion strengthening precipitates [PDF]

open access: yes, 2007
The composition of the sub-15 nm particles in six related vanadium high strength low alloy steels, made by simulated thin slab direct charged casting, has been determined using electron energy loss spectroscopy (EELS). Such particles are considered to be

Effect of small vanadium addition on the microstructure, transformation temperatures, and corrosion behavior of a Cu72Al17Mn11 shape memory alloy

open access: yesJournal of Materials Research and Technology, 2023
In the present work, effects of 0.1 at.% and 0.2 at.% vanadium content on the microstructure, transformation characteristics and corrosion behavior of the Cu72Al17Mn11 shape memory alloy (SMA) have been investigated by means of OM, SEM, XRD, DSC ...

High-resolution two-dimensional quantitative analysis of phosphorus, vanadium and arsenic, and qualitative analysis of sulphide, in a freshwater sediment. [PDF]

open access: yes, 2008
Recently introduced techniques that can provide two-dimensional images of solution concentrations in sediments for multiple analytes have revealed discrete sites of geochemical behaviour different from the average for that depth (microniches).

Friction behavior of laser cladding magnesium alloy against AISI 52100 steel [PDF]

open access: yes, 2012
The use of magnesium alloys in engineering applications is becoming increasingly important as a relatively low density allows savings in energy consumption and therefore reduction in air pollution.

Theoretical application and factors influencing casting settlement of FeV50 alloy

open access: yes工程科学学报, 2017
The process of separation of slag and alloy and distribution of vanadium in casting slag during the casting process of multiperiod FeV50 preparation were analyzed using the principle of infinite fluid gravitational settling. The effects of slag viscosity,

Development of the all-vanadium redox flow battery for energy storage: a review of technological, financial and policy aspects [PDF]

open access: yes, 2011
The commercial development and current economic incentives associated with energy storage using redox flow batteries (RFBs) are summarised. The analysis is focused on the all-vanadium system, which is the most studied and widely commercialised RFB.

Formation of intermetallic and its effect on the hardening of welding joint between vanadium alloy and Hastelloy X alloy after heat treatment

open access: yesNuclear Materials and Energy, 2023
Vanadium alloy and Hastelloy X alloy was jointed by explosive welding (EXW), followed by post-weld heat treatment (PWHT). The formation of intermetallic within the welding joint and its effect on hardening were investigated.
