The influence of the addition of Al(2)O(3) whiskers (2.5wt.% up to 30wt.%) on Vickers hardness and fracture toughness in an Al(2)O(3(n))+ZrO(2) (TZ-3Y)(n) (90, 80 and 70wt.%) composite was investigated. Green compacts were obtained by uniaxial pressing at 50MPa and pressureless sintering at 1500 degrees C in air for 2h. After sintering, relative densities(More)
