In this study, samples with an
Al2024 matrix reinforced with 2 wt.% CNT were produced using the powder
metallurgy method following mechanical milling, and the effects of CNT
reinforcement on physical, microstructural, and mechanical properties were
investigated. The CNT content was reinforced at 2 wt.%, and the milling
duration was set to 8 hours. A Scanning Electron Microscope (SEM) equipped with
Energy Dispersive Spectroscopy (EDS) was utilized for microstructural analyses.
Hardness and tensile strength tests were conducted to determine the mechanical
properties. The results revealed that the high CNT content led to agglomeration
behavior of the reinforcements at grain boundaries. Moreover, the 2 wt.%
CNT-reinforced samples exhibited inferior mechanical properties compared to the
Al2024 alloy. Specifically, the hardness and tensile strength of the Al2024
alloy were measured as 105 HB and 220 MPa, respectively, while the
corresponding values for the 2 wt.% CNT-reinforced composite were 95 HB and 184
MPa. Therefore, it was concluded that the high CNT content adversely affects
the properties of the nanocomposite.
