Abstract
The mechanical loss (Q-1) and Young's modulus (E) were measured as a function of temperature in the range 293K<T<750K on rectangular bar samples of ferroelectric PbZr $_{1\hbox{\scriptsize -}{\rm x}}$Ti$_{\rm x}$O3 ceramics. There are two mechanical loss peaks, which are located below the phase transition point in coarse grained samples and they seem to be associated with the motion of domain walls. One of these peaks are not observed in fine grained undoped ceramics. The use of dopants such as Ge, Bi, Nb produces an attenuation of mechanical loss, a smoothing of elastic modulus anomalies, and a shifting of the phase transition temperatures.
