%. The crack paths, generated by Vickers indentation on the polished surfaces of both composites, were analyzed from a fractal point of view to distinguish the possible toughening mechanisms involved... and toughness is evident: the more irregular the geometry of the crack, the higher the fracture toughness. Key words: Al2O3-TiC-Co; Al2O3-TiC; fractal; toughening mechanism; indentation crack 1 Introduction......
