Competitive Reactions and Formation Mechanism of Microstructures in Mg/Cu Super-Laminate Composites during Initial Hydrogenation

Abstract:

Competitive reactions and formation mechanism of microstructures in Mg/Cu super-laminate composites (SLCs) during initial hydrogenation were studied. During initial hydrogenation of Mg/Cu SLCs, hydrogenation of Mg and alloying of Mg with Cu followed by hydrogenation of Mg₂Cu are competitive. It is found that microstructures of Mg/Cu SLCs during initial hydrogenation have changed drastically depending on the order of hydrogenation of Mg and Mg₂Cu. The microstructures of Mg/Cu SLCs after initial hydrogenation can be categorized in 3 types.
