摘要

Preferred domain orientation of a piezoelectric ceramic develops through domain switching under electric poling. In previous investigations the critical free energy required for domain switching has been assumed as a constant. This assumption leads to overestimation of the poling-induced texture and provides no explanation for the switching reversal in ferroelectric ceramics after the poling field is removed.
