Abstract:


Aims: AA7076 is a well-defined alloy for its excellent physical and mechanical properties such as high strength, toughness, and low density. To meet the requirements of the automobile and aerospace industry, the properties of AA7076 alloy have to be improved by reinforcing nano-sized graphene amine particles.

Objectives: The aim of this study is to synthesize and characterize the AA7076 alloy reinforced with graphene nanofillers for different structural engineering applications.

Methods: In this present work, nano-sized graphene amine particles were added and dispersed homogeneously using a motorized stir casting technique. AA7076/graphene amine composites were prepared by varying wt.% percent of graphene amine reinforcement particles (0.5, 0.75, 1, and 1.25 wt.% (weight-percentage)).

Results: The SEM micrographs reveal the homogeneous distribution of graphene amine reinforcements along the grain boundaries of the AA7076 matrix material. The experimental test results showed that with the addition of graphene amine reinforcements, the mechanical properties of the AA7076/graphene amine composites improved as compared to the AA7076 matrix material.

Conclusion: The composite with 1 wt.% graphene amine showed higher strength and hardness as compared to other reinforcements.
