Abstract
The hydriding kinetics of Mg2Ni are studied below the polymorphic tran sformation temperature of Mg2NiH4 under hydrogen pressures from 4.0 to 10.1 bar. The hydriding reaction of Mg2Ni progresses with the nucleat ion and growth mechanism under these conditions. The nucleation of Mg2 Ni hydride is considered to control the hydriding rates. Heat transfer also decreases the hydriding rates.
