Abstract: (MoNbTiVZr)C high-entropy ceramics (HECs) were prepared by spark plasma sintering (SPS) using carbide powder as raw material. The effects of sintering temperature ranging from 1500 to 2000 ℃ with interval of 100 ℃ on the microstructure and mechanical properties of HECs were studied. The results showed that when the sintering temperature was 2000 ℃, the carbides rich in high melting point Nb and Zr elements were fully dissolved except that a small amount of ZrC was oxidized, and the sintered samples were mainly in (MoNbTiVZr)C HECs phase featuring FCC structure. The density of (MoNbTiVZr)C HECs sintered at 1500~2000 ℃ exceeded 97%. As the sintering temperature rised, the average grain size increased while the hardness and fracture toughness decreased. When the sintering temperature was 1800 ℃, the prepared ceramics had better comprehensive mechanical properties that the hardness and fracture toughness reached (21.44±0.94) GPa and (5.44±0.29) MPa·m^1/2, respectively.
