| Outline of Final Research Achievements |
For a research of fabrication technology on high performance hydrogen isotope storage alloys, Be2Ti, Be2V, and Be2Zr single phase materials were successfully fabricated using by new process. In addition, as a result of a catalyst effect on hydrogen storage capacity in the beryllides, it was obvious that catalysts addition deteriorated the capacity since those formed Be or Ti compounds. In parallel to surveying fabrication technologies, simulation has been carried out with regards to stability of hydrogen atom with an evaluation of its solution energy. A simulation based on first-principles calculation indicated the presence of two hydrogen trap sites, tetrahedral and center of triangle with solution energies of -0.52 and -0.05 eV, respectively, implying that the maximum trap site of hydrogen with 5.4 wt.%
