영어 초록
The present study was focused on the synthesis of a dispersed copper matrix composite material by the combination of the mechanical milling and plasma activated sintering processes. The 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 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 composite material sintered at showed about 98% of theoretical density. The composite material has a hardness of about 130Hv and an electric conductivity of about 85% IACS. The hardness and electric conductivity of composite material were about 140 Hv and about 45% IACS, respectively.
