Abstract Scope |
Carbon nanotubes (CNT) are used as reinforcing materials for lightweight metal matrix composites (MMC) due to their excellent properties such as high elastic modulus and chemical stability. Therefore, in this study, an Al-oxide-MWCNT nanocomposite was fabricated by mechanical milling and hot-pressing, and the microstructure and mechanical properties were evaluated. MWCNTs to improve the mechanical properties of the Al alloy were added in 3 vol.% under all conditions, and the ball-milled powder was hot-pressed at 500 °C under 20 ton. The microstructure and chemical composition according to milling time and powder particle size were confirmed by scanning electron microscopy and XRD, and the interface between Al oxide and MWCNT was analyzed using transmission electron microscopy. |
