Abstract
In this paper regularities in the change of piezoelectric and elastic properties of polycrystalline ferroelectrics are considered in their dependence on changes in the strength of the electric excitation field up to destructive levels at the main vibrational mode. A system of solid solutions from the family Pb(ZrxTi1_x)O3 + yMnO2 where 0.3 < x < 0.7, 0 < y < 3% has been our object of investigation; however, the revealed relationships have a more general character and, apparently, exist in other solid solution systems of PZT as well as, to a large extent, in polycrystalline ferroelectrics in general.Keywords
