AlZrC2 powder prepared by solid-state reaction was sintered using a pulse electric current sintering technique in a temperature range from 1700 to 2000°C under the pressure of 40 MPa in vacuum for 5 min. The density and mechanical properties of the sintered AlZrC2 monolith were estimated. As heating temperature increased, the density of the AlZrC2 monolith increased and the mechanical properties were improved. The bulk density of the AlZrC2 monolith sintered at 2000°C was 5.12 g/cm3. The maximum values of the fracture strength and Vickers' hardness were 380 MPa and 11.1 GPa, respectively.
