Abstract
The hydrogen uptake characteristics of a mechanically milled Ti–Mg–Ni sample processed in accord with that of Lomness et al. [Hydrogen uptake characteristics of mechanically alloyed mixtures of Ti–Mg–Ni. Int J Hydrogen Energy 2002; 27: 915–20] has been shown to rapidly absorb 2.5wt% of hydrogen at 296K. This is significantly less than the 11wt% presented by Lomness et al. but occurs at a lower temperature. X-ray diffraction shows that our ball-milled sample comprises low crystallinity elemental Ti, Mg and Ni which converts to Ti2Ni, Ti and Mg during temperature cycling. Examination of the hydrided sample shows the presence of Ti2NiHx(x>0.5), TiHy(0.7<y<2) and MgH2. Unidentified minor phases are also present.
