| Outline of Final Research Achievements |
In the nuclear and neutron engineering fields, compact and highly stable neutron / gamma ray shielding materials are desired. Metal hydrides are attracting attention because of their good shielding ability and low weight density. However, improvement in toughness and thermal stability is required. In this study, we tried to improve the properties by adding elements that do not form hydride, and by adjusting the microstructure. As an example, a significant improvement in toughness and a shift to higher temperature in the hydrogen desorption temperature were confirmed in a system in Cr-added Zr hydride.
