The hydrogen sorption speeds of $Zr_{57}V_{36}Fe_7$ amorphous alloy and its crystallized alloys were evaluated at room temperature $Zr_{57}V_{36}Fe_7$ amorphous alloy was prepared by ball milling. The amorphous alloy was crystallized through two stages. Initially, $alpha-Zr$ solid solution was appeared from the amorphous phase. Two cubic Laves compounds were precipitated afterwards from the remained amorphous and from excessively saturated solid solution at higher temperature. The hydrogen sorption speed of the partially crystallized alloy was higher than that of amorphous. The enhanced sorption speed of partially crystallized alloy was explained in terms of surface oxygen stability which has been known to retard the activation of amorphous alloys. The retardation could be reduce by crystallization process resulting in the observed increase in sorption property.
