SiC and MWCNT Blending Actions on Functional Performance of Hybrid AA2024 Alloy Nanocomposite Via Two Step Stir Cast Route

The hybrid aluminium alloy matrix composites are adopted in high-strength-to-weight ratio applications with technical benefits, including high strength, good hardness, better stability, and improved thermal stability. This research is enhancing microstructural and mechanical functional behaviours of the hybrid aluminium alloy (AA2024) nanocomposites by the blending actions of nano silicon carbides (SiC) particles and multi-walled carbon nanotube (MWCNT) via a two-step stir cast route. The contribution effect of SiC and MWCNT blending actions on metallography, physical/mechanical qualities, and resistance to corrosion individualities of hybrid AA2024 nanocomposites are studied by the procedure of the American Society for Testing and Materials (ASTM) and compared to monolithic cast AA2024 alloy characteristics. The hybrid AA2024 nanocomposite blended with SiC and MWCNT (weight percentages of 5 and 8%) exposed the specific tailored benefits like homogenous scattered reinforcements resulting in a lower percentage value of porosity (≤ 1%), excellent ultimate tensile strength of 330 MPa with acceptable elongation range of 10%, enhanced indentation resistance capabilities of 128 HV, specific toughness of 15.2 J/mm², and enhanced corrosion performance.
