A measurement of mechanical properties of AA - TiO2 – Gr hybrid composite prepared through powder metallurgy process
Abstract
The hybrid influence of AA - TiO2 - Gr on the characteristics of aluminum powder metal matrix composites (AGCMs) produced using metal powder technology was assessed as part of current work. While keeping the TiO2 mass transfer coefficient steady at 5%, the influence of (Graphite Nano Particles) GNPs weight fractions, 0, 0.5, 1, & 1.5%, on the mechanical and physical properties of the created hybrid nanoparticle were examined.The powders were mixed using a good passing grinding, which would then be carried out by compression and sintering.They studied conductance, nanostructures, ultimate resistance, toughness and other properties.The data confirmed that the mechanical and physical properties of the armature alloy were significantly better than those of the unreinforced matrix.Hybrid TiO2 - Gr partials have been distributed uniformly with no discernible pores in both the electron microscope and also the scanning electron micrograph photos taken with energy dispersion spectroscopy.With an improvement in the percentage weight of partial ceramics, the complex permittivity of the generated aluminium powder composite was also improved, but the dielectric properties were significantly decreased.In addition, sintering samples of the hybrid nanocomposite containing 0.5% GNPS show a uniform organisation of the two reinforcement steps.When the GNPS content was 0.5%, the mechanical properties were 504.6 MPa, which is 31% stronger than AA-5% TiO2.The surface temperature reached the highest level at 0.5% weight GNPs or 345 W/m k.The results suggest an effective method to produce hybrid nanoparticles with high resistance and excellent conductance, which have a wide variety of design uses, including power transfer.
