Abstract

In this study, we effectively manufactured a 0.2 weight percent aluminum-graphene composite by ball milling it for up to 6 hours. The duration of the ball milling trials ranged from two to six hours. Aluminum-graphene composites' microstructural and spectroscopic comparison was explored by assessing their characteristics using XRD, FESEM, TEM, Micro-Raman, and microhardness. It was discovered that the second order disorder peak (2D) increased with milling time. The exfoliation of the composite's graphene is discussed in the Raman spectra of 2D intensity. The extra graphene, at 0.2% weight percent, is harder than the metal. At 600 0C, composites were sintered. The improvement of the D peak in the ball-milled samples proved that the stacking of carbon layers had been separated. In a TEM examination, graphene's sheet-like structure was demonstrated. Composite formation is confirmed by XRD.
