Interphase interfaces in the directionally solidified eutectic (DSE) NiO-ZrO2(CaO) have been investigated using transmission electron microscopy (TEM) techniques. Arguments are presented, based on extensive experimental results, to show that the observed interface plane, (111) NiO//(100) ZrO2, corresponds to a minimum in interface energy. The possible relaxation events associated with this interface are identified with the aid of imaging and diffraction analyses. A recently introduced technique of convergent beam electron diffraction for a plan-view bicrystal is attempted in order to identify rigid body translation associated with this interface. Some of the difficulties associated with this technique are discussed.
