Naturally occurring vanadium is composed of one stable isotope 51 V and one radioactive isotope 50 V. The latter has a half-life of 1.5 × 10 17 years and a natural abundance of 0.25%. 51 V has a nuclear spin of 7/2 which is useful for NMR spectroscopy. Twenty-four artificial radioisotopes have been characterized, ranging in mass number from 40 to 65.
Vanadium er et ikke-magnetisk transisjonsmetall som i ren form er sølvgrått metallisk av utseende. Det er mykt og formbart og har god korrosjonsbestandighet mot lut, svovelsyre og saltsyre.Ved temperaurer over 660 °C oksiderer det lett til vanadiumpentoksid (V 2 O 5).Flere av vanadiumforbindelsene er giftige. Vanadiumstøv er brennbart, og kan medføre lungeskade ved …

The effect of vanadium microalloying on ultra-high strength dual phase (DP) ferrite-martensite steel microstructure and properties was studied. It was found that the addition of 0.14 wt% V to a Fe-0.18C-1.5Mn-0.3Si-0.008N reference alloy introduced very significant ferrite grain size refinement in the cold rolled and annealed state. During ...
Vanadium is a chemical element; it has symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.
