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

在镁/铜复合材料的初始氢化过程中，发生了3个反应：(1)镁的氢化；(2)镁与铜的合金化生成镁铜；(3)镁与铜合金化形成的镁铜的氢化。根据反应的时间，有3个反应过程(1)。反应(1)早于反应(2)、早于反应(3)或晚于反应(3)。这三种反应过程使三种不同类型的显微组织各不相同。而对于镁的加氢，虽然在脱氢过程中出现了明显的孕育时间，但没有出现孕育时间。

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.
