Mechanical properties and slow crack growth (SCG) behavior of a 10Ce-TZP/Al 2 O 3 nanocomposite currently developed as a biomaterial are considered. Fracture toughness is determined for sharp, long (double torsion) and short (indentation) cracks and a good agreement is found between the two types of
