Investigating the Effect of Adding Fe2O3 And SiC on the Mechanical, Electrical and Magnetic Properties of Aluminum Based Hybrid Nano Composites Employing Powder Metallurgy Technique

Abstract

Fabrication of Al/Fe₂O₃+SiC hybrid nanocomposites using the powder metallurgy method is the focus of this study. Different concentrations of Fe₂O₃ (Hematite) (2, 4, 6, 8 and 10wt%) were incorporated into the materials at the same time as SiC (Silicon Carbide) was maintained at a consistent ratio of 5wt%. The synthesized specimens underwent comprehensive testing such as FESEM ( Field Emission Scanning Electron Microscopy) and XRD (X-Ray diffraction) for microstructural analysis; compressive strength, wear resistance and Vickers microhardness for mechanical properties assessment; and electrical conductivity, resistivity, and magnetic hysteresis for evaluation of electrical behavior. Microstructure examinations revealed that SiC and Fe₂O₃ nanoparticles were uniformly distributed throughout the aluminum matrix. In terms of mechanical tests done on this material, there were significant improvements in compressive strength amounting to a 195.20% increase, wear rate which went down by 78.72%, as well as an improvement in microhardness by 44.91% compared with pure aluminum. With the addition of 10wt.% Fe₂O₃, electrical resistivity increased by about 54% whereas conductivity dropped by almost 35.01%. On the other hand, hysteresis loop analysis showed an increase in saturation magnetization (Ms) as well as remanence magnetization (Mr), with increasing amounts of Fe₂O₃ in hybrid nanocomposite. This research signifies transformative progress that can be accomplished when SiC and Fe₂O₃ nanoparticles are strategically infused into aluminum. highlighting their potential for advanced material applications.
