Hydrogen storage properties of melt-spun LaNi 4.25Al 0.75

Rapidly solidified LaNi 4.25Al 0.75 alloy was prepared by melt spinning and its hydrogen storage properties were examined. The hydrogen storage capacities and the equilibrium pressures of the unannealed melt-spun (UMS) LaNi 4.25Al 0.75 alloy were found to be nearly identical to those of the annealed...

Summary:Rapidly solidified LaNi 4.25Al 0.75 alloy was prepared by melt spinning and its hydrogen storage properties were examined. The hydrogen storage capacities and the equilibrium pressures of the unannealed melt-spun (UMS) LaNi 4.25Al 0.75 alloy were found to be nearly identical to those of the annealed induction-melt (AIM) alloy. However, the resistance to pulverization was greatly improved and the hysteresis was markedly decreased for the UMS alloy, while its activation became rather difficult.
