    Abstract
    Young's modulus (Y) of 0.7Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) has been investigated for polycrystals and single crystals oriented along <001>, <110>, and <111>. The value of Y-<001> and Y-<110> for single crystals was dramatically lower than either Y-<111> or the polycrystalline averaged value. For ceramics, field dependent measurements revealed a significant softening of Y, which was not observed for oriented crystals. For both forms, the elastic energy densities were similar, however significantly higher hysteretic losses were found for polycrystals. (C) 2003 American Institute of Physics.
