Abstract
The fracture toughness and flexural strength of Al2O3/Ag composites ar e investigated. Both the strength and toughness of alumina are enhance d as silver inclusions are added. From microstructural observation, th e crack is bridged or deflected by silver inclusions. The toughness en hancement is contributed mainly by the plastic deformation of the silv er inclusions. The strengthening effect is contributed both by the mat rix grain refinement and by the toughness enhancement.
