In the present work, compact of Cu matrix composites reinforced with 5 wt% of TiN were prepared by mechanical alloying and spark plasma sintering method. Influence of sintering parameters on the electrical, mechanical, physical properties and microstructure of copper matrix composite material was investigated. From the results of the measurements, it follows that within the entire investigated temperature range, the density, hardness and electrical conductivity of copper-TiN composites change according to the temperature consolidation changes. It was determined that structure properties and density of sintered material have direct relations to electrical conductivity. Based on the study, it could be concluded that homogeneous distribution of reinforcement phase and maximize reduction of porosity in sintered material should have an impact for electrical conductivity of Cu matrix composites made by powder metallurgy route. A composite of copper and TiN particles reinforcement was prepared by mechanical alloying and consolidated by spark plasma sintering under different temperatures. Electrical conductivity and hardness of the composites change with the temperature of consolidation.Keywords: Powder metallurgy, copper, titanium nitride, spark plasma sintering, mechanical alloying
