Abstract
Recent studies are evaluating the use of particulates fabricated from agro-based residues as
reinforcement for enhancing the properties of aluminium alloys. This report focuses on the
optimization approach and modeling of responses for future prediction, which are absent from
the majority of studies involving particle reinforcement of an aluminum matrix. Herein, palm
kernel shell ash (PKA) and rice husk ash (RHA) were incorporated with 4 wt% of WSD and used as
f
illers in the Aluminium-6061 matrix at variable proportions. The response surface approach was
utilized in the experiment design, modeling, and outcome optimization. The independent vari
ables are the proportions of PKA and RHA and stir casting temperature. Yield, ultimate tensile,
impact strength, elastic modulus, and fracture toughness are examined as response parameters.
The results demonstrated that the microstructural property played a significant role in the re
sponses. Incorporating PKA and RHA into the Al-6061 matrix improved the response parameters.
