Effect of amorphous Mg50Ni50 on hydriding and dehydriding behavior of Mg2Ni alloy

► First study of the hydriding behavior of composite Mg2Ni (25 wt.%) amorphous Mg50Ni50. ► Microstructural characterization of composite material using XRD and SEM was obtained. ► An improved effect of Mg50Ni50 on the Mg2Ni hydriding behavior was verified. ► The apparent activation energy for the hydrogen desorption of composite was obtained.
