Rare earth elements have excellent catalytic effects on improving hydrogen storage properties of the Mg 2 Ni-based alloys. This study used a small amount of Y to substitute Mg partially in Mg 2 Ni 0.9 Co 0.1 and characterized and discussed the effects of Y on the solidification and de-/hydrogenation...
