摘要：

The crack growth resistance behavior of polycrystalline Pb(Zr1-xTix)O-3 has been characterized in a novel experimental arrangement between 24 and 140 degrees C. Experimental measurements were carried out on compact tension specimens submerged in a temperature-controlled silicone oil bath. The results show a decrease in the observed shielding toughness, leading to an overall reduction in the maximum toughness. The temperature-dependent stress strain behavior and elastic properties were characterized, providing an insight into the effect of the changing ferroelastic properties on the temperature-dependent fracture behavior.
