Outline of Final Research Achievements

In this work, the current effects were examined in the high temperature tensile behavior of polycrystalline zirconia ceramics. By applying the DC electric power higher than a critical value, the applied electric current increases sample temperature depending on the applied value, but does not enhance the rate of deformation. For higher than the critical value, on the other hand, the electric current enhances the rate of the deformation to about two times as compared with that of without current conditions. The enhanced deformation cannot be interpreted only by the increment of sample temperatures due to Joule heating. The TEM observation showed that oxygen vacancy areas are formed along grain boundaries. This suggests that the enhanced deformation would be related to oxygen vacancy formation.

Academic Significance and Societal Importance of the Research Achievements

フラッシュ焼結で報告されているように、通電効果の効率的な利用が促進されれば、より低温・短時間で効果的に高機能セラミックスの創性が可能となる。通電効果を活用した高速創製プロセスの実現に向けた要素技術の構築には、通電効果をより効果的かつ効率的に制御するための、その支配因子の解明を通じた制御指針の確立が不可欠である。通電技術を確立することによって、フラッシュ現象の応用先は焼結技術のみに留まらず、革新的な鍛造加工・成形・接合、および修復技術などへの応用展開も見込め、先端産業への波及効果も期待できる。
