Structure of interface in directionally solidified oxide eutectic systems

The morphology and orientation relationships between two phases was investigated in directionally solidified oxide eutectics of ZrO2–MgO, Al2O3–ZrO2(Y2O3) and YIG–Fe3O4 systems using the high-resolution transmission electron microscopic technique. The growth morphology was determined by the volume fraction of the minor phase, the misfit between the two phases, and the growth direction of the eutectics. The interface included misfit dislocations and steps with an atomic height to accommodate the misfit at the interface.
