Experimental Investigation and Comparative Analysis of Aluminium Hybrid Metal Matrix Composites Reinforced with Silicon Nitride, Eggshell and Magnesium

Abstract

In today’s scenario, composite materials play a vital role in automobile, aerospace, and defence sectors because of their higher strength, light weight and other mechanical properties. Aluminium alloy Al6082 is a medium strength alloy with good corrosion resistance properties; hence, it is used for high-stress applications, bridges, cranes, etc. The present work focuses on comparing the mechanical properties of Al6082 and Al6082 with the addition of silicon nitride, magnesium, and bio waste of eggshells. Samples of Al6082 reinforced with 2% of silicon nitride (Si3N4), 5% of eggshell, and 1% magnesium reinforcements were prepared using the crucible casting process. Mechanical properties were evaluated through hardness test, tensile test and compressive tests, which varied with the additives of reinforcement materials. The results showed that the reinforced materials could increase mechanical properties. Further, it will be analysed by the machining parameters involved through the CNC turning process. Analysis of variance from optimisation technique shows a noteworthy increment of material removal rate (MRR) and significant decrement in surface roughness (Ra) and machining time compared to standard aluminium. Additionally, the analysis of mechanical testing has been predicted with the outcomes of stresses and displacements using the ANSYS platform.

An Investigation of the Thermal Properties of LM13- Quartz- Fly-Ash Hybrid Composites

“…To make AMCs viable for large-scale commercial production, it is imperative to reduce the cost of such materials through the selection of proper processing techniques and reinforcements. Researchers are trying to obtain AMCs reinforced with cheaper and easily available materials which include industrial wastes and by-products; this would not only decrease the cost of the final material but also ensure effective waste management [24][25][26]. Quartz (SiO 2 ) is a natural mineral that is hard and crystalline in form.…”

Electroplating on Al6082 Aluminium: A New Green and Sustainable Approach

“…Since fashion-jewellery market players are constantly seeking new, viable ways to render their whole value chain more sustainable, they are constantly looking at making use of green and eco-compatible base materials, yet ensuring economically feasible processes [10][11][12]. Concerning fashion items and accessories like chains, rings, earrings, bracelets and so on, among a wide variety of suitable base materials, aluminium is one of the most interesting because is unlimitedly recyclable and is spread throughout the world, hence is largely available and cheap [13][14][15]. However, aluminium galvanization is challenging, especially when it comes down to the so-called "secondary aluminium" which is aluminium that comes from the recycling process.…”
