    Abstract : In the last decades there has been growing interest in developing ceramic materials with high fracture toughness (KIc) and strength for structural applications. In the specific case of 3 mol % yttria-doped tetragonal zirconia (3Y-TZP), K_Ic can be increased by promoting phase transformation from tetragonal (t) to monoclinic (m) phase in front of a propagating crack tip referred to as transformation toughening.
