✦ Synopsis

The hydrogen storage performance of hydrogenated 34Ti-18Mn-16Cr-(32 -5x)V-x(V 4 Fe) (x = 0, 2, 3, 4, 5) alloys were investigated. It was found that, with the increase of V 4 Fe content, both the lattice parameter and cell volume of BCC phase decrease and the C14 Laves phase is brought into BCC solid solution, which results in the variation of effective hydrogen desorption capacity. Among the studied alloys 34Ti-18Mn-16Cr-17V-3(V 4 Fe) shows the best PCT performance with an effective hydrogen desorption capacity of 1.93 wt% and moderate plateau pressure at 2.84 × 10 5 Pa, which exhibits attractive prospect in practical application.
