description Advanced Materials 17 (2005) 88-91 Mechanical properties of zirconia polycrystals decrease drastically at high temperature due to thermally activated grain boundary (GB) sliding, leading to plastic or even super-plastic deformation. As GB sliding is a source of energy dissipation in the material, mechanical loss measurements are well suited to study such a mechanism. They reveal, in general, a mechanical loss peak, which evolves into an exponential increase at higher temperature. When intergranular glassy films or/and amorphous pockets are presented in polycrystalline ceramics, the mechanical loss is globally higher and so is the creep rate. Here we show that introducing carbon nanotubes in zirconia, in particular, reduces drastically GB sliding and consequently the mechanical loss at high temperature. The nanotubes were observed at the grain boundaries by high-resolution transmission electron microscopy and were related to the reduction of superplasic flow through the boundaries, which should improve the material creep resistance.
