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

ABSTRACTNanocomposites 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.
