摘要	Bulk Ti3AlC ceramic containing 2.68 wt% TiC was prepared by an in situ reaction/hot-pressing route. The reaction path, microstructure, mechanical and thermal properties were systematically investigated. At room temperature Vickers hardness of Ti3AlC ceramic is 7.8 GPa. The flexural strength, compressive strength, and fracture toughness are 182, 708 MPa, and 2.6 MPa center dot m1/2, respectively. Its apparent Young's modulus, shear modulus, bulk modulus and Possion's ratio are 208.9, 83.4, 140.4 GPa, and 0.25 at room temperature. Apparent Young's modulus decreases slowly with the increasing temperature, and at 1210 degrees C the modulus is 170 GPa. The average coefficient of thermal expansion of Ti3AlC ceramic is about 10.1 x 10-6 K-1 in the temperature range of 150 degrees-1200 degrees C. Both the molar heat capacity and thermal conductivity increase with an increase in the temperature. At 300 and 1373 K, the molar heat capacities are 87 and 143 center dot J center dot(mol center dot K)-1, while the thermal conductivities are 8.19 and 15.6 W center dot(m center dot K)-1, respectively.
