Hydriding and dehydriding properties of Mg2Ni/Ni and Mg2 Ni/Ni + 5 wt.% Cu prepared by mechanical alloying

Elemental powders of Mg, Ni and Cu are subjected to high-energy ball milling in order to produce alloys of nominal compositions Mg2Ni and Mg2Ni0: 95Cu0: 05. Nanocrystalline phases based on the Mg2Ni structure are produced after 21 hours of milling. As-milled powders were hydrided for 5 min at temper...
