Elemental powders of Al, Cu, Mg and x wt.% CNT (x: ) were blended and milled in the highenergy ball mill for 4 h. Milled powders of Al alloyCNT composites were subsequently consolidated by upset forging followed by hot extrusion. Even though the particle size of milled powders of Al alloyCNT composites decreased with the addition of CNT, there is no significant effect on crystallite ...

The Crate performance of CNT and Super P was analyzed from to 5 C. In the first C and C, the capacity of CNT cell was slightly higher than Super P cell, and at 1 C both cells showed the same capacity as 147 mAh g −1. After 2 and 5 C, when the current density returns to 1 C, both cells returned their capacity.

Therefore, it is necessary to rationally control the processing parameters to effectively disperse CNT in polymer matrix and avoid the cutting length of CNT and polymer. Although the ball mill is a promising technique used to disperse CNTs in different medium, the mechanism of exfoliation of CNTs should be explored in depth. Melt Extrusion Process

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.
