Diamond-particle-dispersed-aluminum (Al) matrix composites were fabricated in solid-liquid coexistent state by Spark Plasma Sintering (SPS) process from the mixture of diamond and pure Al powders and that of diamond and 5056-type Al-Mg alloy powders. The microstructures and thermal conductivities of the composites fabricated were examined. These composites were all well consolidated at 813K for 2.1ks in SPS process. No reaction at the interface between the diamond particle and the Al matrix was observed by scanning electron microscopy for the composites fabricated under the sintering conditions employed in the present study. The relative packing density of the diamond-Al composite fabricated was 97% or higher in a volume fraction range of diamond between 25 and 45.5%. Thermal conductivity of the diamond-Al composite containing 45.5 vol.% diamond reached 403W/mK, approximately 76% the theoretical thermal conductivity estimated using Maxwell-Euckenís equation.
