The Effect of Milling Mode on the Hydriding Properties of Nanocrystalline Mg2Ni
The paper presents the results of studies of the hydrogen sorption properties of nanocrystalline Mg2Ni intermetallic prepared by mechanical (ball) milling under controlled shearing/impact mode. The pre-alloyed intermetallic powders were subjected to ball milling under various controlled milling conditions such as shearing, high-energy shearing and impact in a magnetic Uni-Ball-Mill 5. The hydriding properties were evaluated by monitoring the absorption PC isotherms by the conventional constant-volume method using Sieverts semi-automatic apparatus. Changes of structure during processing and hydriding properties of nanostructured Mg2Ni intermetallic powders are shown and discussed.
