Paper Title:
Fracture Strength and Damage Resistance of Freeze Cast Alumina/Zirconia Layered Composites
  Abstract

Symmetric three-layer Al2O3/ZrO2 composites have been prepared by freeze casting and pressureless sintering at 1400-1600o C in air. The layered composite with Al2O3 containing 15 vol.% ZrO2 as an outer layer and containing 20 vol.% ZrO2 as an inner layer, sintered at 1600o C showed the maximum bend strength (300 MPa). Contact damage resistance was superior in layered composites compared with monolithic materials, possibly due to the development of compressive stress in the outer layer.
