Abstract
<TEX>$C_{60}$</TEX> 풀러렌이 분산된 알루미늄기지 복합재를 볼 밀링법과 열간압연 공정을 이용하여 제조하였다. 볼 밀링이 진행되는 동안, 알루미늄기지는 그 결정립이 100 nm 이하 수준으로 미세화되어 강화되었다. 동시에 <TEX>$C_{60}$</TEX> 풀러렌이 알루미늄기지 내에 균일하게 분산되어, <TEX>$C_{60}$</TEX> 풀러렌의 첨가량이 증가할수록 복합재의 강도가 증가하였으며, 10 vol%의 <TEX>$C_{60}$</TEX> 풀러렌을 포함하는 순 알루미늄기지 복합재는 1 GPa 수준의 압축 강도를 나타내었다. Aluminum-based composites containing <TEX>$C_{60}$</TEX>-fullerenes are produced by hot rolling of ball-milled powder. The grain size of aluminum is effectively reduced to ~100 nm during ball-milling processes, leading to grain refinement strengthening of the composite. Furthermore, <TEX>$C_{60}$</TEX>-fullerenes are gradually dispersed during ball-milling processes and hence the strength of the composite increases with the volume of <TEX>$C_{60}$</TEX>-fullerenes. The composite containing 10 vol% <TEX>$C_{60}$</TEX>-fullerenes with a grain size of ~ 100 nm exhibits ~1 GPa of compressive strength.
