Abstract :
Nanocrystalline yttria tetragonal zirconia polycrystals (YTZP) with different amounts of an amorphous phase have been deformed at moderate temperature (1150 °C) and at constant strain rates. The aim of this work was the study of the influence of that glassy phase on the mechanical response of these nanocrystals. Transmission electron microscopy (TEM) analysis and atomic force microscopy (AFM) pictures of the deformed and as-received samples have been carried out in order to determine the grain size distribution and clarify the possible deformation mechanisms.
