4. Conclusion
In-situ Al-4.5%Cu/10%TiC metal matrix composite was
successfully fabricated using stir casting route. Ti was
added in elemental form and activated charcoal powder
was added in the melt which resulted into the formation
of Titanium Carbide as reinforcement. As the reinforce-
ment phase was formed inside the melt (In-situ process),
the distribution of Titanium Carbide was seen to be more
uniform. The yield, ultimate tensile strength and hardness
were seen to increase by 12.64%, 19.72%, and 35.79%
respectively in the composite material with TiC as rein-
forcement. The fracture surface of tensile sample shows
small dimples indicates ductile fractures. Tensile strength,
fracture surface and hardness of Al-4.5%Cu/10%TiC
MMC fabricated in the present investigation indicated
improvements of material properties.
