Abstract

This study produced silicon carbide (SiC) and aluminum oxide (Al₂O₃) particulates using an in situ reaction system of silicon dioxide (SiO₂)+ carbon (C)+ aluminum (A)l with a molten aluminum alloy. The reaction system was examined through differential scanning calorimetry (DSC). The in situ-fabricated aluminum matrix composites (AMCs) were analyzed through X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), electron backscatter diffraction (EBSD), and transmission electron microscope (TEM). The electromagnetic (EM) shielding effectiveness of the fabricated AMCs was measured in the frequency of 1–5 GHz. The heat flow curve obtained from the DSC analysis revealed the temperature required to attain the reaction. The XRD pattern confirmed the formation of SiC and Al₂O₃ particulates. FESEM micrographs confirmed that the SiC and Al₂O₃ particulates were distributed along the intergranular region in the AMCs. The in situ-synthesized submicron-level particulates enhanced the mechanical properties of the composites. The hybrid AMCs exhibited considerable EM shielding effectiveness.
