Goal is to gain an understanding of the nature of interphase interfaces, phase-equilibria and phase transformations in ceramic systems which have high potential for property improvement through transformation toughening. We have focused our attention on studies concerning: (1) the nature of interphase interfaces in zirconia based eutectics, and (2) the effects of ternary additions on the growth kinetics of precipitates in magnesia partially stabilized zirconia (Mg-PSZ) ceramics. We have been able to use our understanding of twinning behavior to explain the nature of twin structure present in ceramic superconductors.
