The as-cast Mg_2Ni-type Mg_(20-x)Y_xNi_(10)(x=0,1,2,3 and 4) electrode alloys were prepared by vacuum induction melting.Subsequently,the as-cast alloys were mechanically milled in a planetary-type ball mill.The analyses of scanning electron microscopy(SEM),X-ray diffraction(XRD) and transmission electron microscopy(TEM) reveal that nanocrystalline and amorphous structure can be obtained by mechanical milling,and the amount of amorphous phase increases with milling time prolonging.The electrochemical measure...
