Technological watch

The utilization of aluminium and magnesium-based alloy materials are ranked as one and two positions for the various lightweight applications due to their enhanced physic-mechanical characteristics compared to other metals. This research is an attempt to fabricate the aluminium alloy (Al-Si) alloy hybrid nanocomposite by using 20wt% of waste aluminium alloy scrap recycled metal powder particle via stir casting technique, and its characteristics are enhanced by the additions of 3, 6, and 9wt% of silicon carbide (SiC) nanoparticle. The synthesized aluminium alloy, nano, and hybrid nanocomposite are subjected to physical, microstructural, and mechanical characteristics study. The density of the composite obeys the rule of mixture and increases progressively. The surface morphology revealed a homogenous distribution with little slag and agglomerated particle formation. The HNC2 hybrid nanocomposite (Al-Si/20wt% waste metal powder/6wt% SiC) offered high microhardness (74.21?±?1.85HV), impact strength (12.98?±?0.17 J/mm2), and tensile strength (148?±?1.42 MPa) and elongation percentage (12.8%). The optimum value of the HNC2 sample was suggested for automotive alloy wheel applications.
