Effects of SiC particulate-reinforced on the fluidity and mechanical properties of Aluminium Matrix Composite through stir casting route

Abstract

Stir casting method has been widely known to produce Aluminum matrix composite (AMC). Fluidity is a critical parameter to determine casting component with free of defects, especially for thin wall part. This study aimed to analyze fluidity and mechanical properties of AMC. Analysis of fluidity of molten metal was performed using a carbon steel spiral permanent mold. Moreover, hardness and density are characterized to investigate of additional reinforcing phase. Experiment results show that the fluidity length of AMC melts increase with the additional percentage of SiC particulate. Furthermore, hardness and density result show maximum hardness is obtained in a maximum composition of SiC particulate. Analysis morphology using SEM revealed that the failure mode of fracture is the combination of ductile and brittle mode.
