In the present work an effort is made to confirm the presence
of actual weight percentage of reinforcements and its effect
on aluminium alloy composites during stir casting technique.
Two types of reinforcements such as Silicon carbide and Boron
carbide were used by varying weight percentage to manufacture
Al6061 composites. The manufactured composites after
stir casting shows uniform distribution of hardness on the entire
cross section measured from top to bottom. The dissolved
composites during acid test shows approximately 95% of reinforcements
present in the aluminium composites. Presence
of reinforcements play a very important role to enhance the
mechanical properties of aluminium alloy by altering the microstructure
during solidification and induces strain energy in
the metallic matrix alloy. Almost 50% increase in hardness and
40-50% increase in tensile strength were observed in the as cast
composites as compared to aluminium alloy. Uniform distribution
of reinforcements and hardness distribution on the entire
cross section clearly reveals that stir casting is the effective
method for manufacturing aluminium composites.
