摘要：

In this study, high pressure and high temperature sintering (HPHT) is adopted in the cermet fabrication process, and the microstructure and mechanical properties of cermets with TiC0.5N0.5-15WC-10Mo(2)C-5TaC-10Ni-10Co (wt%) sintered under 5 GPa and different temperatures (900-1600 degrees C) using 6 x 14 MN cubic press are investigated. Results show that the densities of samples can reach up to 7.00 g/cm(3). Vickers hardness and fracture toughness of the products are over 1727 HV30 and 72 MPa m(1/2) respectively. In addition, the sintering results are compared with the data that obtained from commercial samples which produced via conventional sintering technique. The conclusion is that high density and high hardness cermets can be obtained through HPHT sintering. (C) 2015 Elsevier Ltd. All rights reserved.
