| Outline of Final Research Achievements |
To fabricate high-performance thermal management materials with ultra-high thermal conductivities and low CTEs, metal-matrix composites (MMCs) containing high thermal conductive fillers were fabricated. To avoid the damage of filler particle surfaces, spark plasma sintering (SPS) processing was used as a processing technique. Al, Cu and Ag powder were used as matrix materials, and diamond, SiC, and cBN powder were used as filler particles. Various kinds of MMCs, Al/Diamond, Al/cBN, Al/SiC, Cu/Diamond and Ag/Diamond, were fabricated by SPS process. Al-matrix composites were fabricated in solid-liquid co-existent state and thermal conductivity higher than 500 W/mK was obtained. Ag matrix composite could be successfully fabricated by valuable solidus ratio type consolidation. Bimodal filler particle effect was confirmed for these Al matrix and Ag matrix composites. The addition of B and Cr were effective for thermal conductivity enhancement of Cu/Diamond composites.
