| Abstract: | Indentation behavior of Ce-TZP, Y-TZP, and Mg-PSZ between room temperature and 1300°C was investigated. Hardness decreased with increasing temperature for all three materials, but indentation cracking increased with increasing temperature. The opposing temperature dependences are discussed in terms of dislocation and transformation plasticity. |
