Mechanical Alloying of Mg2Ni Hydrogen Storage Alloy

>

After milling for 20 days, Mg2Ni has produced about 36 J.1mparticles as measured by particle size distribution and scanning electron microscopy. At this stage Mg2Ni alloy phases was formed as proven by X-ray diffraction. Energy-dispersive analysis analyses show that the elemental percentage of Mg and Ni is 67.8 % and 32.2 %, respectively. Those which are suitable for use as hydrogen storage alloy in nickel metal hydride batteries. Keywords: Mechanical Alloying, Mg2Ni alloy, X-ray diffraction. A.
