| Summary: | Stir casting method is used in the production of SiC reinforced-aluminium metal matrix
composite (AMMC) to enhance the properties of base metal. Different weight fraction of Silicon
carbide, SiC (5 wt%, 10 wt% and 15 wt %) particulate-reinforced AMMCs are fabricated and
characterizations of physical and mechanical properties of the materials are performed based on the
experimental. The microstructure of the fabricated composite material are studied and analyzed.
The results indicate that the mechanical properties of the composite, including yield strength, tensile
strength and hardness are enhanced by the increment of the weight fraction of reinforcing phase.
Nevertheless, the elongation and fracture toughness of the composite decreased as the reinforcing
phase increased. This is mainly due to the brittleness of the SiC particles which act as micro void
initiator. |
