| Outline of Final Research Achievements |
The goal of this study was to obtain fundamental knowledge for the development of high performance hydrogen storage Mg/Cu super laminate composits utilizing ultrasonic welding technique. Temperature measurements, identification of reaction layers and microstructural characterization were conducted using ultrsonic welds between Mg and Cu. Consequently, nanosized Mg2Cu intermetallic compound layer could be obtained at the ultrasonic weld interface. The growth rate of the intermetallic compound layer was found to be larger than ten thousand times in comparison with the normal growth rate of Mg2Cu layer. Additionally, Mg/Cu laminates with nanosized Mg2Cu intermetallic compound layers in every interface could be achieved in a single ultrasonic welding.
