| Abstract: | The temperature dependence of Young's modulus and internal friction (Q?1)in alumina, silicon nitride, and partially stabilized zirconia (Y-PSZ) ceramics was studied. Little change in Q?1 was found for alumina, whereas Q?1 for silicon nitride ceramics increased above 700°C. The Q?1 of Y-PSZ increased markedly with increasing temperature up to a peak at ～200°C. |
