Experimental investigation on the mechanical properties of Al2024 doped with green synthesized quantum dots

ABSTRACT

This work used a novel technique known as powder metallurgy to create Aluminium (Al) 2024 matrix composites using Al 2024 reinforced with graphene quantum dots at concentrations ranging from 0.25 to 1 wt.%. Here, Al alloy 2024 is presented as a metal matrix composite reinforced with graphene quantum dots. Graphene quantum dots (GQDs) are fragments of graphene that are smaller than 100 nm in size. Graphene quantum dots are added to Al 2024 in proportions of 0.25%, 0.5%, 0.75%, and 1% to create composites. Atomic force microscopy, X-ray diffraction analysis, Fourier transform infrared, TG/DTA, transmission electron microscopy, and scanning electron microscopy experiments have been carried out to determine the characteristics of the synthesized GQD nanoparticles doped with Al 2024. This powder metallurgy process in Al 2024 offers a number of advantages. Shape and material flexibility, application variety, and cost-effectiveness are all made possible by these characteristics. The results showed that powder metallurgy is a suitable method for incorporating and dispersing nanoparticles into Al 2024.
