| 内容記述 | Be12Ti and Be12V are promising candidates for neutron multipliers in solid breeding blankets, which is used in a bulk form to achieve the fuel tritium self-sufficiency. Previously, significant anisotropic thermal expansions were predicted for Be12Ti and Be12V along different crystallographic axes using density functional theory (DFT) calculations. Nevertheless, empirical confirmation through experimental data on thermal expansion anisotropy remains lacking. In this study, the thermal expansion behaviors of these materials were experimentally investigated by using high-temperature X-ray diffraction. Diffraction data were collected temperatures up to 873 K under vacuum condition, and structural refinement was carried out by Le Bail analysis using a partial structure. The results demonstrate that these materials exhibit moderate anisotropic expansion along the c-axis direction, contrary to previous prediction for Be12Ti. The average thermal expansion coefficients were compared with those of ceramic breeder pebble beds and structural steel material to discuss thermo-mechanical compatibility in a breeding blanket. | |||||||||||
