    In this work, the synthesis and machinability studies are presented for a new TiC ceramic and MoS2 soft particulate reinforced aluminium alloy 7075 (AA7075) matrix composite (AMCs). The results show that the AMCs have improved machinability compared with the base AA7075. The chip morphology is changed from continuous sheared chips in AA7075 to discontinuous chips in AMCs. The change is caused by the reduced ductility in AMCs due to reinforcement TiC and MoS2 microparticles. The surface roughness is increased for the AMCs when compared to that of base alloy due to hard TiC particles.
