Resumen:
ABSTRACT  The catalytic effect of secondary phases contained in the alloy ZrCrNi on its electrochemical properties was studied. Samples of the as-melted alloy were subjected to annealing treatments at T = 1250 K during different times in order to vary the amounts of remaining microsegregated secondary phases. The electrochemical hydrogen absorption of these samples was studied by charge-discharge cycling, high rate dischargeability (HRD) and electrochemical impedance spectroscopy (EIS). The correlation between the measured properties and the secondary phases present in the alloy is discussed.
