| Research Abstract |
3 reactions have happened during the initial hydrogenation of Mg/Cu super-laminate composites: (1) a hydrogenation of Mg, (2) an alloying Mg with Cu to Mg2Cu, (3) a hydrogenation of Mg2Cu formed through an alloying Mg with Cu. There exist 3 reaction processes depending on the timing of the reaction (1). : The reaction (1) occurs earlier than the reaction (2), earlier than the reaction (3), or later than the reaction (3). The three reaction processes make 3 types of microstructures different from each other. And about a hydrogenation of Mg, an incubation time does not appear although a clear incubation time appears during a dehydrogenation of MgH2.
