Reinforcing potential of Irvingia wombolu shell particulates in Al-2Nb-0.5Si eco-composite

Abstract: The primary objective of this research is to investigate the potential of IWSp as reinforcement in Al-2Nb-0.5Si eco-composites. The study aims to assess various mechanical properties and microstructural characteristics to determine the effectiveness of IWSp as a reinforcing material. The Al-2Nb-0.5Si eco-composites were fabricated using the stir-casting technique. This process involves mixing the aluminum matrix with varying percentages of IWSp (1%, 3%, 5%, and 7% by weight) to create composite samples for testing. The microstructure of the developed composites was examined using an optical microscope (OM). The results indicate that the IWSp were evenly dispersed in the aluminium matrix. This even dispersion is crucial for enhancing the properties of the composites. The addition of IWSp led to an increase in the ultimate tensile strength of the Al-2Nb-0.5Si matrix, with a maximum value of 174 MPa achieved. The hardness of the composites also increased with the inclusion of IWSp, reaching a maximum value of 288 HV. The impact energy of the composites improved, reaching a maximum of 49.1 J. However, there was a sudden decrease in impact energy when IWSp was incorporated above 1wt%. The alloy matrix exhibited a better percentage elongation value compared to the composite samples, with a maximum value of 42%. The study concludes that IWSp has the potential to serve as an alternative reinforcing material for Al-2Nb-0.5Si eco-composites.
