Performance Evaluation of Nano Silicon Carbide Configured Aluminium Alloy with Titanium Nanocomposite via Semisolid Stir Cast

<div class="section abstract"><div class="htmlview paragraph">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.</div></div>
