Al2O3/Ni laminated composites were prepared by aqueous tape casting and hot pressing with intent to study mechanical properties including the fracture strength and toughness. The residual stress was evaluated and proved. The relations of mechanical properties with the thermal residual stress, the ductility of metal layers and the layer thickness ratio were studied, respectively. It was found that the toughness and work of fracture of Al2O3/Ni laminar reached to 12.56 MPa m(1/2) and 12450 J m(-2), which are 3.6 and 478.8 times that of pure Al2O3. (c) 2005 Elsevier B.V.
