Magnesium Alloy / Hydrogen Storage / Amorphous Phase / Mechanical Alloying / Electrochemical Capacity The effect of ball mill modification with Ni on the microstructure and electrochemical properties of La 2 Mg 17 based and CeMg 12 based hydrogen storage alloys was characterized. The amount of the added Ni was one of the key factors controlling the earlier formation of homogenous amorphous phase for the ball-milled composites. The results of the study indicate that the electrochemical
