Abstract

Misch-metal (Mm) substituted (Ti_0.16Zr_0.05Cr _0.22V_0.57)1-xMmx (x = 0.0, 0.03, 0.05, 0.10) alloys were synthesized by arc-melting. Phase analysis and microstructural studies were carried out using powder X-ray diffraction (XRD) and transmission electron microscopy (TEM) techniques. The proportion of phases was estimated by Reitveld analysis of the powder X-ray diffraction data. The addition of Mm results in a decrease in the hydrogen storage capacity as well as a change in structure. The DTA analysis shows two endothermic peaks from ZrCr₂H₄ and BCC hydride.
