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.
期刊介绍:
The International Journal of Metalcasting is dedicated to leading the transfer of research and technology for the global metalcasting industry. The quarterly publication keeps the latest developments in metalcasting research and technology in front of the scientific leaders in our global industry throughout the year. All papers published in the the journal are approved after a rigorous peer review process. The editorial peer review board represents three international metalcasting groups: academia (metalcasting professors), science and research (personnel from national labs, research and scientific institutions), and industry (leading technical personnel from metalcasting facilities).
