Abstract
This study has addressed the feasibility of synthesising and recycling a silicon carbide reinforced magnesium composite using an innovative disintegrated melt deposition technique with the aim of improving the mechanical properties. Microstructural characterisation studies revealed a marginal decrease in porosity and reinforcement content, and no change in grain morphology, reinforcement distribution pattern, and interfacial integrity between matrix and reinforcement following recycling. Results of physical and mechanical property characterisation revealed increases in 0.2% yield strength, ultimate tensile strength, ductility, and coefficient of thermal expansion of the recycled specimens when compared with the parent composite. These properties have been rationalised in terms of the microstructural characteristics associated with the disintegrated melt deposited composite specimens. Particular emphasis was placed on studying the effect of recycling on the microstructure and properties of the composite.
