Abstract :The Al-7xxx series alloys exhibit exceptional high strength, corrosion resistance, and excellent finishing characteristics, making them a common choice for manufacturing automotive and aerospace components. To further enhance the mechanical and structural properties of these alloys, they are often reinforced with alloy powders. This study focuses on Alumix 431, an Al-7xxx series alloy, and glass powder obtained through the grinding of waste glass. The primary aim of this research is to evaluate the use of glass powder as a reinforcement material in metallic alloys, such as aluminum alloys, with a particular emphasis on utilizing waste materials. The impact of glass powder on the surface and structural properties of Alumix 431 has been systematically examined. A homogeneous mixture was achieved by blending the alloy with 15% (wt) glass powder. Subsequently, this homogeneous mixture was subjected to a 0.6-ton shock pressure and underwent a heat-treatment process at a temperature of 650 °C in a furnace for a duration of 1 hour. The physical properties of this composite material, including hardness, density measurements, surface topography, and microstructural properties, were characterized using optical microscopy, scanning electron microscopy images, energy-dispersive X-ray spectroscopy spectra, and X-ray diffraction analysis for crystal structure determination. The incorporation of glass powder into the alloy resulted in improved hardness and density properties. The maximum hardness and bulk density values were achieved with the Alumix 431-15% GP alloy, measuring 41.846 N/mm² and 2.451 g/cm³, respectively. Conversely, the minimum apparent porosity and water absorption values were observed in this composite material, measuring 2.293% and 0.935%, respectively. Furthermore, the study determined the occurrence of various phases, such as Al2CuMg, diopside, cristobalite,, between Alumix 431 and glass powder.Keywords : Al-7xxx alloys, Alumix 431 alloy, powder metallurgy, structural property, surface morphology
