High-strength, lightweight aluminium-based composites show great potential for
future weight-reduction applications. The aluminium alloy (AA5052) is commonly
used in various engineering applications and serves as the primary matrix
material for this study. The objective of this research is to produce and
improve the properties of the AA5052 alloy composite by integrating titanium
(Ti) and nano silicon carbide (SiC) particles using an advanced vacuum stir
casting process. Additionally, an inert atmosphere is used to minimize voids,
porosity, and oxidation. The final developed composites include AA5052,
AA5052/3wt% Ti, AA5052/5wt% SiC, and AA5052/3wt% Ti/5wt% SiC, which were
subjected to metallographic, tensile, elongation, and hardness studies. The
mechanical evaluation is carried out following ASTM E8 and E384 standards.
Microstructural analysis revealed uniform dispersion of Ti &SiC particles
with no significant casting defects. The composite with AA5052/3wt% Ti/5wt% SiC
exhibited the highest tensile strength, elongation, and hardness, measuring
243MPa, 34%, and 93HV, respectively. The contribution of Ti and SiC with an
effective interface with the AA5052 matrix is the reason for the enhancement of
mechanical behaviour.
