Abstract
In this study, a high-melting point element, flake type graphite (Gr.), was added to aluminum (Al) to improve the latter’s thermal properties. Al with different particle shapes, spherical, irregular and flake shape, was mixed with graphite. Al–50 vol.% Gr. powders were mixed by a shaking mixer and sintered under the..... More

Abstract
The use of heat dissipation materials in various field such as power semiconductor device, LED and microelectronic system. Therefore, there is a need for heat dissipation materials using copper (Cu) and graphite (Gr). These materials have high thermal conductivity. In particular, graphite has high thermal stability with a low coefficient..... More

Abstract
In this study, a high-melting point element, tantalum carbide (TaC) was added to improve the mechanical properties and the oxidation/corrosion resistance of Fe. The Fe-TaC composites were synthesized by high energy ball milling for the mechanical alloying of the non-equilibrium phase (Fe-Ta) and the homogeneous dispersion of TaC. Fe-TaC composite..... More
