Mg2-yAlyNi(y=0,0.2,0.3,0.4) and Mg2-aTiaNi (a=0.1,0.2,0.3,0.4) were successfully synthesized by two-step process. The phase composition, microstructure and morphology of the alloys were determined by XRD and SEM. It was found that their main phase was Mg2Ni and another phase, Mg3AlNi2, was observed when Mg in Mg2Ni was partially substituted by Al. The SEM observations showed a large amount of white grains were uniformly distributed in the matrix of the alloys substituted by Al, Ti and the variation of microstructure led to promoted electrochemical properties.
