Analysis and characterization of TiO2 nanoparticle effect on aluminum matrix nanocomposites by stir casting.
English abstract
The objective of this study was to use stir casting to create aluminum matrix nanocomposites with a
uniform dispersion of TiO2 nanoparticles to evaluate their effect on the performance of aluminum-based products.
Microstructural analysis significantly reduced the grain size, with an average drop of 18.2%. This suggests that the
TiO2 nanoparticles affect the mineral matrix, which improves the mechanical properties. With the incorporation of
TiO2 particles, the results showed improvements in stiffness (6.97%), nominal stress (27.92%), actual failure stress
(25.6%), and ultimate stress (26.1%). Outperforming commercially pure aluminum, the mechanical properties of
the resulting nanocomposites were significantly improved by adding TiO2 nanoparticles into the aluminum matrix.
Microstructural and X-ray diffraction (XRD) studies confirmed the beneficial effects of the addition of
nanoparticles.
