The grain refinement of aluminium alloy has the potential for various engineering
utilization like automotive, marine, and aviation. Besides, the choice of grain
refinement influences better performance and compatibility action. Aluminium
alloy processed with zirconium grain refinement, high cost and risk of grain
coarsening reasons, this research focused on Ti-C grain refinement with sodium
modifier for T6 processing by aluminium alloy (AA6013) made by stir cast route.
Impacts of Ti-C grain refinement with sodium modifier T6 processing on
microstructural behaviour, hardness, and tensile performance are investigated,
and the hardness and tensile are followed by ASTM E384 and ASTM E8 standards.
The AA6013-T6 (1:1 Ti/C) with 0.15Na is found to have better grain refinement
and found the TiC particle during the casting process, which leads to better
enhancement of overall mechanical behaviour. The hardness, ultimate tensile,
elongation percentage, and Young's modulus of AA6013-T6 (1:1 Ti/C) with 0.15Na
are 71%, 72%, 28%, and 23 % better than the value of the base alloy. This grain
refined aluminium alloy is utilized for automotive top roof frame usage.
