The latter becomes possible by a transient liquid phase generated by a TiH2 additive which enhances the densification in a similar way as MgO/Y2O3. Oxide doping, however, increases the number and the size of amorphous triple junctions, favours the formation of transformation resis- tant t'-ZrO2 and deteriorates strength and toughness.enceramic compositesKompositkeramiksinteringSinternsubstoichiometric TiCTiCtransformation resistant ZrO2 phasetransient liquid phasetransiente flüssige PhasezirconiaZrO2666620conference paper
