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.... The resulting toughening effect is largely due to crack deflection mechanism besides grain refinement effects. The crack profile (or irregularity) then is closely related to the crack deflection......
