Paper Title:
Effect of Ti Content on Hydrogen Storage Properties of Amorphous MgNi Alloy
  Abstract

Cycle capacities of Amorphous Mg-Ni alloys declined so fast therefore they can’t be used practically. In this paper,the influence of adding Ti on the discharge capacity and cycle stability of the alloys were investigated. Amorphous Mg1-xTixNi (x=0, 0.1, 0.2, 0.3) alloy powder was prepared successfully by mechanical alloying (MA). X-ray diffraction (XRD) results show that MgNi alloy formed completely amorphous phase after ball milling with 15h. But for Mg1-xTixNi (x=0.1, 0.2, 0.3) alloy, it took 23h. It can be concluded that Ti partial substituting Mg would decrease the amorphous phase forming ability of Mg-Ni based alloy. Compared with amorphous MgNi alloy, the maximal discharge capacities of Mg1-xTixNi (x=0.1, 0.2, 0.3) alloy were decreased slightly, but the cycle stabilities were significantly enhanced. Mg0.9Ti0.1Ni alloy showed the largest discharge capacity and the best cycle stability.
