中文摘要	The dense polycrystalline Ti3AlC2 ceramics are produced by hot pressing using SHS Ti3AlC2 powders as starting materials. The sintered activation of the powders is better than using Ti, Al (or Al4C3) and C as raw materials by hot pressing. The optimal sintering temperatures of SHS Ti3AlC2 powders is from 1400 degrees C to 1500 degrees C. The density, Vickers hardness, bending strength and fracture toughness of the Ti3AlC2 ceramics sample by hot pressing at 1450 degrees C for 2 h under pressure of 25 MPa and in Ar atmosphere are 99.50% 112 of the theoretical value, 2.8 GPa, 426.02 MPa and 10.08 MPa center dot m(1/2), respectively. The densities and fracture toughnesses of sintered samples are increased with the increment of sintering temperature, but the bending strength are decreased above 1400 degrees C.
