    A structural study of the hydrogen absorption properties by replacing vanadium with zirconium in metal alloys
    (2016) Bellon Monsalve, Daniela; Martínez Amaríz, Alejandro David; Barreneche Sarmiento, Diana-Patricia; Dos Santos, D S
    Hydrogen storage and microstructure the TiCrV0.9, TiCrV0.9Zr0.2 and TiCrV0,7Zr0.4 alloys were investigated. The alloys were melted in arc furnace, the structure was analysed by X- ray diffraction and hydrogen absorption times were analysed by Sievert’s type apparatus. The results showed that the addition of Zr replacing the V decreases in the absorption capacity passing of 3.8%wt to 2.0%wt in contrast the speed of hydrogen absorption increases considerably.
