| Outline of Final Research Achievements |
Fine intermetallic compounds were homogeneously dispersed inside the matrix for when the reaction time was 300 s (applied pressure of 0.4 MPa, temperature of molten alloy, 973 K. The counts of the intermetallic compounds, showed an increasing trend with decreasing reaction time (300 s) for the same area analysis. The average area of the intermetallic compound showed a decreasing trend with decreasing reaction time. The vickers hardness and flexural strength of the composite obtained at a reaction time of 300 s are 198.8 Hv and 239.5 MPa, higher than that obtained under the other fabrication conditions. The thermal conductivity of the intermetallic-compound-reinforced composite is 112.53 W/mK, which is higher than the thermal conductivity observed for the composites fabricated at a reaction time of 60 s and 600 s. However, the thermal conductivity of the composite was almost similar to that of the matrix, A366 alloy.
