AbstractThe goal of this research is to study the microstructural analysis and mechanical properties of an aluminum matrix reinforced with different amounts of nano Fe3O4 at (2, 4, 6, 8, and 10wt. %). Al/ Fe3O4 nanocomposites specimens were prepared using the powder metallurgy route. Many examinations, including Field Emission Scanning Electron Microscopy (FESEM) and X-Ray Diffraction (XRD) analysis, were performed on the specimens in this study to determine the microstructure and phases of the nanocomposites. Mechanical tests, such as compressive, microhardness, and wear tests, were also performed to assess the mechanical properties of the nanocomposites. The results of this study show that Fe3O4 nanoparticles have been homogeneously dispersed in the Al matrix by FESEM and XRD examination. While the mechanical tests show improving the compressive strength at 6 wt.% by 5.36%, the highest microhardness was at 10% by 101.6% compared with the pure Al, and improving the wear rate.
- Al/Fe3O4 nanocomposite were successfully fabricated by powder metallurgy method.
- The microstructure examinations showed homogeneous distribution to Fe3O4 nanoparticles in Al matrix.
- Compared to other weight percentages, the nanocomposite with 10 wt.% of Fe3O4 has highest microhardness and low wear rate.
- Compared to other weight percentages, the nanocomposite with 6 wt.% of Fe3O4 has highest compressive strength.
