“…Zr-based amorphous and nanocrystalline alloys are also used in a number of applications because of their mechanical properties [4][5][6]. On the other hand, high numbers of tetrahedral coordinated sites for interstitial hydrogen make these alloys a good candidate for hydrogen storage application [7,8].…”

“…3) in comparison with its crystalline counterpart. In the literature, there is no consensus on storage properties of the amorphous form (by quenching, ball-milling, and annealing) versus its crystalline form of the same chemical composition, e.g., different results include lower capacity [2,37À41], similar capacity [42], higher capacity [43], faster desorption rate [39,43], and better high-rate dischargeability [37,40]. It will be interesting to find that, although the impact of HIA to capacity is controversial, the improvement to the high-rate capability from HIA is universal.…”

Available online xxxKeywords: Hydrogen absorbing alloys Hydrogen induced amorphization Metal hydride electrode Transmission electron microscope Re-crystallization a b s t r a c t Hydrogen induced amorphization (HIA) of the LaMgNi 4 phase at 30 C was found in three LaMgNi 4 /LaNi 5 two-phase metal hydride (MH)-forming alloys. The amorphizationhappened at the first dehydrogenation cycle from a fully hydrided alloy, and the process is reversible after annealing at 250 C for 1 h. The hydrogen storage capacity of the LaMgNi 4 phase in an amorphous state is higher than in its crystalline form. A scanning electron microscope study did not observe any significant changes in the shape of grains as a consequence of HIA and re-crystallization. A transmission electron microscope study confirmed the amorphous structure of the LaMgNi 4 phase after HIA. These findings suggest a new way to improve the performance of MH alloys when used in electrochemical applications.
