摘要：

Mg-x wt% ZrCrCo (x = 25, 50) composites are prepared by high energy milling. These composites are studied in terms of their structural, morphological, and hydrogenation properties. XRD results suggest no reaction between Mg and ZrCrCo not only after milling but also after hydriding treatment. Both counterparts are found to be converted in their hydride state on hydrogen exposure. The maximum storage capacity is found to be 5.4 and 3.8 wt% at 300 degrees C for x = 25 and 50 respectively in Mg-x wt% ZrCrCo composite. The presence of alloy phase greatly enhances the sorption kinetics even at lower temperature. The composite with 50% ZrCrCo content could desorb 90% of its total hydrogen capacity within 60 min at 250 degrees C, while it takes less than 10 min to desorb its total capacity at 300 degrees C.
