摘要：

The fracture mode of lead zirconate titanate (PZT) ceramics at room temperature is investigated as a function of grain size. The fracture mode is almost intergranular at small grain size and changes to predominantly transgranular at large grain size. Application of an electric field (poling) causes a change in the fracture mode from transgranular to intergranular. The observed fracture behavior of PZT ceramics is explained in relation to a possible domain structure. Copyright © 1990, Wiley Blackwell. All rights reserved
