FIG. 1.

Hydrogen desorbed fraction vs time at various temperatures for the Mg sample with mixed Fe–Zr additives at (◻) , (○) , (▵) , (◇) , (★) , and (▷) . In the inset, we present the Arrhenius plot of the desorption rate constant . The straight line is the least square fit.

FIG. 2.

Hydrogen desorbed fraction vs time at of sample with Zr (▵), Fe (○), and Nb (◇) single additives and mixed Fe–Zr additives (◻). The lines are only a guide for the eyes.

FIG. 3.

XRD spectra pertinent to Mg samples with mixed Fe–Zr additives (completely activated) after desorption. In the figure, only the Fe reflection peaks are labeled and all others peaks are pertinent to reflections. In the inset we present the Fe (110) reflection peak pertinent to a sample with only the Fe additive, line (a), and to a sample with mixed Fe–Zr additives, line (b). The thick line is the reference position of the Fe (110) peak (Ref. 12).
