Comprehensive research about an extraction of improving factor for hydrogen absorption/desorption properties and high functionality of laminate type hydrogen storage alloys

Mg/Cu超级叠层复合材料在初始氢化过程中发生了3个反应：（1）Mg的氢化，（2）Mg与Cu合金化生成Mg_2Cu，（3）Mg与Cu合金化生成Mg_2Cu的氢化。根据反应（1）的时间，存在3个反应过程。反应（1）比反应（2）早、比反应（3）早、或比反应（3）晚发生。这三个反应过程使三种不同的微观结构。关于Mg的氢化，虽然在MgH 2的脱氢期间出现明显的孵育时间，但未出现孵育时间。

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.
