Abstract

In the present investigation an effort has been made to produce Al-Fly ash green composite using liquid state stir casting technique followed by green ultrasonic vibration such that it can improve wettability of fly-ash with aluminium by adding magnesium in the presence of argon gas. Addition of magnesium increases wettability of fly-ash particle in the molten aluminium and improves mechanical properties of Al-Fly ash green composite to a great extent. Incorporation of magnesium enhances the homogeneous allocation of fly ash particles in the pure aluminium alloy. More uniform distribution of Fly ash provides better mechanical properties. In this study, sample of Al/2 wt.% Mg/8 wt.% Fly ash provides most excellent outcome amongst all the selected composition. Microstructures show that the distribution of reinforcements is more uniform in this composition. TEM image shows proper wettability between aluminium and reinforcements. Density, cost estimation, hardness, toughness, ductility and tensile strength were also calculated to observe the result of magnesium and fly ash addition in aluminium matrix.
