Thixotropic Mg alloys have been focused only on the aspect of semi liquid forming until now. In the present study, with the aim of improving hydrogen storage capacity, we kept an eye on the microstructural evolutions and chemical properties of thixotropic microstructure in Mg-(3, 6, 9, 12 mass%) Ni alloys by using a partial remelting process. According to the results of pressure-composition-isotherm (PCT) measurements and image analysis, Mg rich solid phases were regarded as the hydrogen absorbing phases and eutectic regions (quenched liquid phase) were considered as the catalyzer to improve hydrogenation kinetics. Especially, the hydrogenation properties depended on the properties of globules and liquid fractions.
