In this study, CNT-reinforced
Al2024 matrix nanocomposite powders were produced using the mechanical milling
method. The research focused on investigating the effects of CNT reinforcement
on the properties of Al2024 matrix powders, including powder morphology,
particle size and distribution, and microhardness of the particles. The CNT
content was reinforced at a weight fraction of 2%, and the milling duration was
set to 8 hours. To examine the powder morphology and assess the extent of CNT
incorporation into the powders, a Scanning Electron Microscope (SEM) equipped
with Energy Dispersive Spectroscopy (EDS) was employed. Additionally, an
advanced computer-assisted laser particle size analyzer was utilized to
determine the particle size and distribution within the powders. The
microhardness of the powders was evaluated using a multifunctional digital
hardness testing device. The results revealed significant changes in the powder
morphology with 2% CNT reinforcement, showing a tendency for the powders to
acquire spherical and flaky structures. The particle size distribution of the
nanocomposite powders exhibited a broader peak compared to the Al2024 matrix
powders, while the average particle size was significantly reduced.
Furthermore, the particle hardness of the nanocomposite powder was found to be
considerably higher than that of the Al2024 matrix powder.
