The present study was focused on the synthesis of a TiB_2 dispersed copper matrix composite material by the combination of the mechanical milling and plasma activated sintering processes. The Cu/TiB_2 mixed powder was prepared by the combination of the mechanical milling and reduction processes using the copper oxide and titanium diboride powder as the raw material. The synthesized Cu/TiB_2 mixed powder was sintered by the plasma activated sintering process. The hardness and electric conductivity of the sintered bodies were measured using micro vickers hardness and four probe method, respectively. The relative density of Cu/TiB_2 composite material sintered at 800°C showed about 98% of theoretical density. The Cu-1vol%TiB_2 composite material has a hardness of about 130Hv and an electric conductivity of about 85% IACS. The hardness and electric conductivity of Cu-3vol%TiB_2 composite material were about 140 Hv and about 45% IACS, respectively.
