Abstract
Swiftly advancing technology is compelling the scientific community around the world to invent new class of advanced materials and reinvent existing materials to produce high performance materials like metal matrix composites. Metal matrix composites have proven their significance from time to time with their superior mechanical properties, low weight, and high wear resistance. But the cost of production of such composites limits their applications on a broad spectrum. In the current study, welding slag, an industrial by-product, is repurposed as reinforcement to produce economical and eco-friendly aluminum-based metal matrix composite because welding slag is produced in large quantities across industrial and construction sector and produces a hefty amount of pollution that harms the environment. Highly corrosion- resistant and structural Aluminum AA-7075 alloy is reinforced with varying percentages of welding slag particles (0-12%) by weight, and the effects of reinforcement percentage on hardness, strength, ductility, and impact energy of the material are investigated. The results showed an improved mechanical strength and high hardness in composites. Impact energy has also improved to a significant extent at higher concentrations of reinforcement particles.
