摘要：

Ferroelectric fatigue in (1-x)Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) polycrystals was investigated in the tetragonal (x = 0.3) and rhombohedral (x = 0.4) phases in ceramics conventionally and hot-pressed prepared. It was found that for the conventionally prepared samples the fatigue was independent of the kind of electrode employed and did not reveal any influence of the crystal symmetry. Nevertheless, for the hot pressed samples, the electrodes had a strong influence on the fatigue behavior, being higher for the tetragonal composition.
