中文摘要The densi?cation of hot-pressed ZrN ceramics doped with Zr or Ti have been investigated at 1500–1700 ? C. It is shown that either Zr or Ti additive can facilitate the densi?cation process. ZrN with 20 mol% Zr or Ti (named ZNZ and ZNT) sintered at 1700 ? C can achieve above 98% relative densities whereas densi?cation temperature up to 2000 ? C is necessary for pure ZrN. The densi?cation improvements are attributed to solid solution of Zr or Ti into ZrN to form non-stoichiometric ZrN1?x or (Zr, Ti)N1?x. The microstructures and mechanical properties of ZNZ and ZNT samples have been examined. Large grain size and ?at fracture surface existed in ZNT sample sintered at 1700 ? C, which lead to poor toughness as low as 2.3 MPa m1/2 . On the contrary, the fracture toughness of ZNZ sample sintered at 1700 ? C was up to 5.9 MPa m1/2 , attributed to ?ne and uniform grain size distribution.
