Alumina-zirconia laminated composites have been fabricated by warm pressing and sintering tapes. Such composites contain large residual stresses and the fracture mode indicates strong bonding between the layers. Transmission electron microscopy studies of the interfaces show that there is no interdiffusion or second phase present. The boundary consists of strongly interlocked grains. In the zirconia a 2 μm interfacial zone transforms due to the large residual stresses. Constraint of the transformation is thought to lead to clamping forces responsible for the strong interface behaviour.
