采用扫描电镜（SEM）、透射电镜（TEM）、XRD、XPS和拉曼光谱（Raman spectroscopy）研究了碳纳米管（CNTs）在机械铣削过程中的结构演变。研究表明，单独铣削CNTs会引入缺陷，但保留了管状结构。当用铝（Al）粉研磨碳纳米管以制备复合材料时，拉曼光谱显示大多数纳米管被破坏。在碳纳米管/铝研磨混合物的烧结过程中，从纳米管的破坏中获得的碳原子与铝反应形成碳化铝（Al4C3）。研究了铣削对铝基体的影响。
The structural evolution of carbon nanotubes (CNTs) during mechanical milling was investigated using SEM, TEM, XRD, XPS and Raman spectroscopy. The study showed that milling of the CNTs alone introduces defects but preserves the tubular structure. When milling the CNTs with aluminum (Al) powder in order to produce a composite, Raman spectroscopy has shown that most of the nanotubes are destroyed. During sintering of the CNT/Al milled mixture, the carbon atoms available from the destruction of the nanotubes react with the Al to form aluminum carbide (Al4C3). The effect of milling on the Al matrix was also studied.
