Abstract
The time dependence of PZT (lead zirconate titanate) (Navy I and III) was investigated in the case of a high stress applied parallel to the poling axis. The time dependence was found to be linear in ln(t), with slope activated in temperature with an activation energy of 0.29-0.32 eV for the Navy I material and 0.62-0.80 eV for the Navy III material. The slope was also found to be linear in stress. It is postulated that this time dependence is due to reorientation of the 90° domains in the sample
