Abstract Scope |
The utilization of eco-friendly green plant waste materials as reinforcing agents in aluminium alloy-based composites represents a sustainable and environmentally responsible approach to material development. The primary objective of this research is to explore the reinforcing characteristics of Irvingia wombolu shell nanoparticulates (IWSNp)/carbon nanotubes (CNTs) hybrid on the electrical and thermo-mechanical properties of Al-7Si-2Cu-0.5Ni eco-composite. The CNTs were synthesis from Rice Husk. The IWSNp and CNTs were prepared using a sol-gel technique. The IWSNp and CNTs hybrid were in the ratio 2:0.5, 2:1, 2:2, 0.5:2, and 1:2. The eco-composites were inoculated by Al-Nb-V-Zr master alloy and subjected to thermo-mechanical treatment (cold worked/homogenized/hot worked/aged at 450oC and 480oC for 2-12h) to produce a high strength, super electrical and thermal conductivity ultrafine-grained Al7SiCu0.5Ni/IWSNp/CNTs eco-composite. The microstructure evolution and Phase compositions of the eco-composites were analyzed using Optical Microscope, Scanning Electron Microscope (SEM), X-ray Diffractometer (XRD), and Energy Dispersive Spectroscopy (EDS). |
