The internal friction (Q - 1) in multiple-components ceramics PZT type was measured as a function of temperature from 300 to 600 K. An internal friction peak (P2) appears a few dozen degrees below Curie temperature (TC). The P2 peak of internal friction is found to be associated with the viscous-elastic mobility of domain walls. The internal friction due to the viscous-elastic mobility of domain walls was calculated and compared with the experimental data.
