High‐resolution electron microscopy was used to image incoherent ZrO 2 /Al 2 O 3 interfaces in ZrO 2 ‐toughened Al 2 O 3 containing intragranular ZrO 2 . These particles are generally spherical but are sometimes faceted. High‐resolution electron micrographs provide atomic‐level information on the interfacial structure. For spherical particles, both ledgelike images and misfit dislocation‐like images accommodated the lattice misfit, depending on the orientation of the interface, while faceted particles imply at least one low‐energy ZrO 2 /Al 2 O 3 interface.
