| Abstract: | 80.6wt.%B4C/11.6wt.%TiB2/4.7wt%Mo/3wt.%C ceramic composite is fabricated by hot-pressing sintering and the effect of sintering temperature, holding time and pressure on mechanical properties and microstructure of the composite are analyzed. The temperature is raised from 1800℃ to 1950℃, the holding time ranges from 15min to 60min and the pressure is 30-35MPa. The strength, hardness, toughness and densification of the composite prepared by the optimized process of 1900℃ under 35MPa for 45min are 705MPa, 20.6GPa, 3.82MPa·m1/2, 98.2%, respectively. |
