Fig. 2 shows the XRD scans for AlCNT powders milled for 3 and 6 h, respectively. A small peak is observed at 26° corresponding to (0 0 2) of graphite for powders ballmilled for 3 h, but then disappears after milling for 6 is interesting to note that in previous published work that applied ball milling for 5 min, a clear peak at 26° was not observed, despite the TEM observation of ...

The dispersion of carbon nanotubes (CNTs) is the bottleneck in CNTreinforced metal matrix composites. In this work, CNT/Mg composites were prepared by grinding Mg powder and then dispersing CNTs via ball milling and hot pressing. The uniform distribution of Nicoated CNTs in the matrix was achieved by optimizing the content of CNTs. Scanning electron microscope, highresolution transmission ...

Alternatively, ball impact treatment (BIT) can be used to Al/CNT plating on Al substrates. This method has been applied by using planetary ball mills and vibratory ball mills. For example, Romankov et al. [10] successfully used mechanical alloying (ball impact treatment) to obtain intermetallic coatings TiAl in a vibratory ball mill.
