Abstract

Hydrogenation was undertaken in MgNi₂ after intense straining by the process of high pressure torsion (HPT). Despite the general acceptance that MgNi₂ is not a hydrogen absorber, quantitative analysis demonstrated that the HPT process introduced the capability of hydrogen storage in MgNi₂. Although the total hydrogen content was not sufficient, the hydrogen storage performance clearly appeared in the MgNi₂. XRD analysis suggested that the hydrogen should be present at grain boundaries.
