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.....

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.....

DOI:
https://doi.org/10.3365/KJMM.2020.58.8.533
Abstract
In this study, consolidated WC-Fe compacts as a function of Fe contents were fabricated by a spark plasma sintering method, following the mixed by the ball-milled powder. Fe among the metallic binders was added to WC enhance not only the driving force of sintering process but also suppressing the grain.....
