The present work reports the impact of granite marble powder (GMP) and SiC on the physical, microstructural, and mechanical characterization of the hybrid aluminium-based metal matrix composite (AMC). Al-4032/SiC/GMP composites with 4, 6, and 8 weight % of SiC and GMP (equal proportion) have been fabricated through stir casting. The impact on properties like density, porosity, ultimate tensile strength (UTS), elongation, microhardness, and impact strength were analyzed according to ASTM standards. A maximum of 1.07% increase in theoretical density and a maximum of 4.86% decrease in experimental density have been recorded for 8% reinforcement. Microstructure of the as-cast specimens were analyzed using optical microscope (OM), XRD (X-ray diffraction), and SEM (scanning electron microscope) equipped with EDS (energy dispersive spectroscopy). Owing to ceramic particles, mechanical properties like UTS, microhardness, and impact strength of the AMC got enhanced from 69.4 MPa to 146 MPa, 131.4 HV to 190.2 HV, and 22.4 J to 32.8 J, respectively.

“…[11][12][13] However, the decision to use a composite structure is typically influenced by the trade-off between its manufacturing costs and performance in terms of weight reduction. 14 Hybrid particulate reinforced aluminum matrix composites (HPRAMCs) are a new category of MMCs with the ability to meet modern demands for innovative industrial applications. 15 These requirements are addressed by HPRAMCs' superior physicomechanical, tribological, and corrosion resistance properties, adaptability to current processing techniques, and the prospect of lowering manufacturing costs.…”

This study investigates Hybrid Particulate-Reinforced Aluminum Matrix Composites (HPRAMCs), a material class known for exceptional physico-mechanical, tribological, and corrosion resistant properties. The research synthesizes HPRAMCs using SiC, Al2O3, graphite (Gr), and sugar cane bagasse ash (SCBA) reinforcements through a powder metallurgy process, followed by sintering at 550°C for 3 h. Comprehensive tests include X-ray diffraction (XRD) for phase analysis, physico-mechanical assessments, tribological evaluations, and corrosion resistance analyses. Notably, secondary reinforcements significantly reduce porosity, with AS4 HPRAMC exhibiting a 0.53% porosity, while AS1 HPRAMC has 1.446%. AS4 HPRAMC displays a remarkable 209.76% increase in compressive strength and a 446.40% boost in material hardness compared to pure aluminum. Secondary reinforcements also improve tribological performance, reducing wear loss by 60.27% and the coefficient of friction by 89.89%. Exceptional corrosion resistance, with an inhibition efficiency of 99.691%, is observed in the AS4 HPRAMC sample, confirmed by scanning electron microscopy (SEM). These findings underline the substantial potential of HPRAMC materials, positioning them as promising candidates for aerostructural components, aircraft systems, automobiles, spacecraft, and high-performance engineering applications.
“…The PCM and Nanoparticles used in the bar plate are achieved at about 92°C by Palanikumar et al [4]. Seshappa and Prasad [5] was developed in different five weight fractions (0, 3, 6, 9, and 12%) to develop aluminum-based nano-composites and have modified in this sample of gas injection ultrasonic probe double-stir casting process. It is concluded that of benchmark against compatible alloys and metallic implants.…”
An experimental analysis of a stepped solar box cooker (SSBC) improved using energetic SiO2/TiO2 nanoparticles. They were used in different ratios between 5% to 25% as a coating on a bar plate to enhance thermal performance. The SSBC was assessed experimentally to obtain a costeffective solution and the best performance for the bar plate temperature, enabling increased cooking activities performance. The furious SiO2/TiO2 nanoparticles were coated over a bar plate, which allows them to absorb more solar radiation and increase the system of inner moist air temperature. The SiO2/TiO2 nanolayers used as 15% improved overall thermal efficiency by 31.42% of the system. The bar plate performances coated with SiO2/TiO2 nanolayers and used in SSBC were compared to other doping nanoparticles percentage for their solar thermal characteristics. The SiO2/TiO2 nanolayers coated by the SSBC is enabled to increase the performance by about 31.77%, 37.69%, 49.21%, 36.99%, and 34.66% when was used 5%, 10%, 2 15%, 20%, and 25%, respectively and compared to that of single nanolayers (SiO2, TiO2) of convention cooker.
