Creep behavior of nanocrystalline monoclinic ZrO2

Creep of nanocrystalline monoclinic zirconia, grain sizes of 75, 125, 175 nm were tested at 950 and 1000 °C. Dynamic grain growth occurred during creep but results were corrected for grain growth. Creep behavior followed an n=1.7 and p=3 behavior. It is proposed that grain boundary sliding is an active mechanism and results fit with Coble creep behavior.
