| Outline of Final Research Achievements |
Spontaneous infiltration experiments using alumina balls with different Ni nanoparticle distribution revealed that the distribution of Ni nanoparticles would influences the infiltration process. The results of XRD analysis of the Ni nanoparticles before and after the heat treatment, only NiO was detected after the heat treatment. Therefore, it was found that spontaneous infiltration would be achieved due to the thermite reaction between NiO and molten Al alloy. Furthermore, by utilizing the mechanical milling technique to join the metallic particles on the surface of the reinforcements, it is suggested that Cu particles with a small particle size, which has high plastic deformability, would be suitable to be joined to the surface of SiC particles and the amount of Cu adhering to the SiC particle surface could be increased under high energy milling conditions.
