Ultrasonication and microwave processing of aluminum alloy- Graphene - Al₂O₃ nanocomposite

ABSTRACT

Nanocomposites with Graphene and Al₂O₃ (particulates) as reinforcement combinations with various proportions (weight percentage) in aluminum alloy AA 2024 and AA 2219 matrix with 30 to 40 µm are processed through vacuum hot press and microwave processing approach. X-ray diffraction and Raman spectroscopy analysis was done on developed nanocomposites to study the Graphene peaks, carbide formation, and other deformation on added Graphene in the nanocomposites during microwave processing. Microstructural, compressive, and diametrical tensile strength analyses were also carried out on developed composites. Effect of Graphene addition in combination with Al₂O₃, on strengthening mechanism during microwave sintering, had been discussed.
