Název v původním jazyce
Temperature dependence of Young's modulus and damping of partially sintered and dense zirconia ceramics
Popis výsledku v původním jazyce
Young's modulus and damping of partially sintered and almost fully dense zirconia ceramics (tetragonal zirconia polycrystals with 3 mol.% yttria), obtained by firing to different temperatures (range 1000-1400 degrees C), have been determined via impulse excitation, and the evolution of Young's modulus and damping of partially sintered zirconia with temperature has been monitored from room temperature to 1400 degrees C and back to room temperature. The room-temperature Young's modulus of the partially sintered materials obeys the Pabst-Gregorova exponential prediction, which is relatively unusual for partially sintered materials. With increasing temperature Young's modulus decreases, until the original firing temperature is exceeded and sintering (densification) continues, resulting in a steep Young's modulus increase. During heating and cooling the temperature dependence obeys a master curve with a typical inflection point at approximately 200 degrees C, the temperature where damping (internal friction) exhibits a maximum. The reasons for this characteristic behavior of doped zirconia are recalled.
