| Summary: | Aluminium 6061 (AA6061) plays an important role in modern engineering
due to its versatile applications, including aerospace, automotive, and
construction. This study explores AA6061 as a matrix material reinforced
with walnut shell ash (WSA) and Silicon Carbide (SiC), produced through the
ultrasonic-assisted stir casting technique. The research aims to improve the
process parameters using the Taguchi L9 orthogonal array. The parameters
include weight percentage of reinforcement - 2% (1%WSA+1%SiC), 4%
(2%WSA+2%SiC), and 6% (3%WSA+3%SiC), Stirring speed (SS) -300 rpm,
350 rpm, and 400 rpm, and Stirring time (ST) -2, 3, and 4 minutes. The
response properties examined are hardness, impact strength, and
compressive strength. Optimal parameters for achieving maximum
hardness are 6% reinforcement, 300 rpm stirring speed, and 2 minutes of
stirring time. For optimal impact strength, the best conditions are 2%
reinforcement, 300 rpm stirring speed, and 2 minutes of stirring time. For
maximum compressive strength, the ideal parameters are 6%
reinforcement, 400 rpm stirring speed, and 3 minutes of stirring time.
Scanning Electron Microscope (SEM) images confirmed the uniform
distribution of reinforcements, supporting the results. This study
demonstrates the impact of optimizing process parameters to improve the
mechanical properties of AA6061 composites, contributing significantly to
their potential applications. |
