A new approach for recycling, fabrication, and heat treatment of al base composites reinforced with rice husk ash particles

Abstract

As a novel combined environmental toxicology technique to reduce the environmental hazards to humans, the utilization of agriculture waste as a novel waste material recycling process in aluminum metal matrix composites has been getting more attention to fabricate and improve the properties of this kind of composites. In this study, a new kind of metal matrix composite reinforced with rice husk ash particles has been fabricated. In the first step, the Al base composites reinforced with rice husk ash particles were fabricated via the compa casting process and the second step was the study of their mechanical, electrical, physical and wear properties. It also highlights the current application and future potential of agriculture-industrial waste-reinforced composites for various applications with a focus on material manufacturing in vessels, automobiles and other construction industries. Also, the annealing was performed after ARB on fabricated composites. Different elongation can happen during heating and annealing since the thermal expansion coefficients of composite samples are not equal and could weaken the strength of the interface. The examination unveiled that composites containing 10% by weight of RHA particulates exhibit superior mechanical and wear resistance compared to monolithic samples. Moreover, the average Vickers hardness of the samples increased from 154.0 to 168.0 for monolithic and 10% RHA samples, respectively, marking a 9% improvement. © 2024 Elsevier Ltd
