| Outline of Final Research Achievements |
The distribution and dispersibility of the dispersoid or the reinforcement in metal matrix composites with practical metals such as aluminum, copper, steel and so on was controlled by using various 3D structural control techniques, and then the composites with anisotropic structure and properties was obtained. Especially, the composites with high thermal conductivity with special direction was obtained. The relationship between the properties and anisotropic microstructure was analyzed theoretically by using computer simulation, then the guideline of the design and manufacturing technique of the practical composites with high and anisotropic thermal conductivity was obtained.
