Abstract
In the present investigation, Cu-SiC and Cu-diamond composites with different volume percent of reinforcements were produced by vacuum hot pressing. Copper powder with different amount of SiC and diamond were hot pressed at 1000°C for 0.5 h at an applied pressure of 32 MPa. The achieved sintered density of the composites was in the range of 94-98 %. The sintered density decreased with an increase in the amount of SiC and diamond. Hardness of the composites improved with an increase in the volume percent of the reinforcements. Hardness of the Cu-30 vol.% diamond and Cu-30vol. % SiC composites was 88 VHN and 104 VHN, respectively.
