| 内容記述 | A new combined plasma sintering and rotating electrode method for fabricating beryllide rods and pebbles has been suggested. Using these methods, preliminary synthesis of ternary beryllide pebbles with different chemical compositions, Be12Ti1−xVx (x = 0.1, 0.3, 0.5, 0.7, 0.9 and 1.0), was successful. Scanning electron microscopy observations revealed that grain size on the surface decreased, whereas the area fraction of the Be phase in the cross-section decreased as the amount of V increased. These decreases may be attributed to the fact that the chemical composition of the pebble was closely varied to single-phase Be12V, with no peritectic reaction as the amount of V increased, while the Be, Be12Ti, and Be17Ti2 phases were formed with large grains caused by a peritecic reaction in Be12Ti. This feature influenced the variation of reactivity with 1% water vapor at high temperatures. It was concluded that weight gain and H2 generation decreased with decreases in grain size as well as Be phase on the surface, as the amount of V increased in Be12Ti1−xVx. Based on cross-sectional observations after oxidation measurement for 24 h, we found that Be12Ti0.3V0.7 and Be12Ti0.1V0.9 pebbles showed high phase stability. | |||||
