摘要：
Mg1.7M0.3Ni (M = Mg, La, Nd and Ce) alloys were prepared by vacuum induction melting under the high purity helium atmosphere. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were utilized to study the phase structures of tested alloys, and their morphologies and hydrogen storage properties were intensively studied by pressure-composition -temperature (PCT) test. It was found that the Mg-M-Ni(M=Mg, La, Nd and Ce)alloys appeared multiphase structures, and as Nd substituting Mg the Mg-Nd-Ni obtained the optimal activation behavior, plateau characteristics, hydrogen cycling reversibility and kinetic properties.
