An investigation is conducted of the characteristics of Al2O3 ceramics which have undergone 'double reinforcement' through incorporation of both ZrO2 and SiC whiskers, with a view to the optimization of such ceramics' properties for metal-cutting tool applications. Both hardness and fracture toughness are found to increase with SiC whisker level, and then exceed a maximum as the ZrO2 level is increased. Tetragonal-to-monoclinic transformation is enhanced with rising SiC and ZrO2 levels. Transformation toughening and whisker toughening are the dominant toughening mechanisms. 7 refs.
