The structure and mechanical properties of electrophoretically deposited t‐ZrO 2 /Al 2 O 3 lamellar composites are described. The fracture behavior of, and crack paths in, such composites with strong interfaces has been evaluated using indentation and 4‐point bend tests. The effect of residual and induced stresses is considered. It is shown that significant crack deflection can be obtained in t‐ZrO 2 /Al 2 O 3 composites by incorporating a number of closely spaced, thin Al 2 O 3 layers.
