N2 - Alloys of the hypo-eutectic Mg-Mg2Ni system can be modified by trace elemental additions which change the microstructure and the functional properties. The modified microstructure results in improvements to the hydrogen storage properties. In alloys of optimal composition, it has been shown that the reversible storage of 6.5-7wt% H2 is possible at a rate of reaction that is realistic for industrial applications. This paper discusses the mechanism of hydrogen release in air at atmospheric pressure with in-situ crystallographic phase transformation analysis obtained by synchrotron radiation X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS).
