Duplex ceramics: II. Strength and toughness

摘要: Abstract Strength and toughness of various sintered HiPed duplex ceramics are investigated. It is found that the strength reduced increased compared with respective matrix data. The transformability ZrO2 particles in incorporated zones examined. retained after a mechanically introduced surface damage, i.e. their mechanical damage resistance, improved when to pure matrix. An attempt made relate normalized strength, toughness, resistance an internal stress intensity factor, Ki, generated around pressure zone.
