Abstract

The effect of Al and Zn additives on the grain size of Mg-3Ni-2MnO 2 alloy was investigated. The nanostructured Mg-3Ni-2MnO2 and Mg-3Ni-2MnO2-3Al-Zn were made by ball milling process under hydrogen atmosphere. The XRD results and TEM analysis reveal that Al and Zn additives almost have no effect on the grain size of Mg-3Ni-2MnO2 alloy. The present study provides us a feasibility of producing nano-structured magnesium alloys, based on hydrogenation, disproportionation, desorption and recombination(HDDR), by adding beneficial elements to hydrogen storage materials.
