| Outline of Final Research Achievements |
The behaviors of hydrogen-induced superabundant vacancies in electrodeposited metals were analyzed and the application of hydrogen-induced effects to the structural control of functional alloy films was investigated. The room-temperature grain growth proceeded concurrently with hydrogen desorption in the electrodeposited Cu films of high hydrogen concentrations. For the electrodeposited Pt/Co and Ni/Cu diffusion couples, with the thermal desorption of hydrogen, the grain growth proceeded, while the alloy layers were not formed. The lattice contraction was observed in the electrodeposited metals of high hydrogen concentrations and the structures of carbon-vacancy-hydrogen clusters in the electrodeposited Fe-C alloy films were calculated from the changes in the lattice parameter and the concentrations of carbon and hydrogen. The behaviors and concentrations of hydrogen-induced superabundant vacancies were different for different metal species and depositing conditions.
