A series of Ti3AlC2/ZA27 composites have been successfully synthesized by mechanical alloying and pressureless sintering, which use the mixed powder of Ti3AlC2 and ZA27 as raw material. The effects of sintering temperature on composition, microstructure and mechanical property were investigated. The results showed that the relative density, Vickers hardness, bending strength and tensile strength were improved with increasing sintering temperature from 600?C to 870?C. Both the bending strength and tensile strength reached the maximum values of 592 MPa and 324MPa, respectively, at the temperature of 870?C. A weak reaction between Ti3AlC2 and ZA27 took palce at 870?C and led to the good bonding between the reinforcements and the matrix.
