decreasing trend with temperature as the temperature decreases (Figure 3.7). The<br />

resistivity of nanocomposite is higher than that of the 2024 Al alloy. Agglomeration of<br />

carbon nanofibers does not occur for this MA-prepared composite. Much more work<br />

is needed to elucidate this problem.<br />
