The results indicated that the orientation relationship between MgH2 and Mg during the phase change was: one of the zone axis of MgH2 <110> parallel to Mg [0001] zone axis, or one of the plane {110} of MgH2 parallel to the basal plane of Mg (0001). On the basis of the obtained results, we proposed a structural model for the phase change of MgH2 to Mg.ElsevierJournal Articleapplication/pdfhttp://hdl.handle.net/2115/45175https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/45175/1/IJHE36-5_3600-3605.pdf0360-3199International Journal of Hydrogen Energy365360036052011-03enginfo:doi/10.1016/j.ijhydene.2010.12.017author
