Application of a novel method for fabrication of graphene reinforced aluminum matrix nanocomposites: Synthesis, microstructure, and mechanical properties

Mechanical and Thermal Evaluation of Aluminum Hybrid Nanocomposite Reinforced with Alumina and Graphene Oxide

“…Carbon materials such as carbon fibers [ 20 , 21 ], graphite [ 22 , 23 ], carbon nanotubes (CNTs) [ 24 , 25 ], graphene (G) [ 26 , 27 ] and graphene oxide (GO) [ 28 , 29 ] have been used as reinforcements in Al-MMCs. In graphene-reinforced aluminum matrix nanocomposites, an improvement of 79, 49 and 44% in yield strength, ultimate strength, and Vickers hardness have been reported with 1 wt.% GO addition, and the increase in GO content has led to grain refinement of the composite [ 30 ]. In another study, an increase in GO has yielded an increase in the hardness of Al-GO composites up to 0.4 wt.% GO, with a maximum increase of 163.8%, but the hardness has declined upon increasing the GO reinforcement to 0.6 wt.%.…”

Plastic Deformation of Metal/Graphene Composites with Bimodal Grain Size Distribution: a Brief Review

“…2d and 2e) demonstrates the existence of very fine cracks. Also, the presence of pulled out graphene has been observed [41] on the fracture surface of Al-Cu/1RGO nanocomposite. This implies that microcracks formed during tensile testing of this composite can decrease its ductility.…”

“…In particular, Kurapova et al [40] and Khoshghadam-Pireyousefan et al [41] produced metal/graphene composites with the Ni [40] and Al-4Cu [41] matrices characterized by bimodal grain size distributions. The Al-4Cu/graphene composites have shown an improvement of 79%, 49% and 44% of yield strength, ultimate strength, and Vickers hardness, respectively, for the nanocomposite containing 1 wt.% of graphene in comparison to the unreinforced Al-4Cu alloy (Fig.…”

Aluminum nanocomposites reinforced with monolayer polyaniline (C3N): assessing the mechanical and ballistic properties

“…Their results revealed that the mechanical properties of the sintered nanocomposites, such as the yield stress, ultimate stress, and Vickers hardness improved to 79, 49, and 44%, respectively, with only 1 wt% graphene as reinforcement over the Al-4Cu alloy. 27 The mechanical properties of pure 2D materials such as graphene, boron nitride, and C 3 N have been studied in detail using molecular dynamics simulations. [28][29][30] Reports indicate that the 2D hexagonal structures greatly inuence the properties, and especially mechanical characteristics of aluminum composites.…”

“…The most important of these models are the shear lag model, the orowan looping effect, and the hallpetch equation. 27 Therefore, in this paper, using a molecular dynamics simulation technique, the mechanical parameters (such as yield stress and strain) were investigated along with Young's modulus of an aluminum nanocomposite reinforced with different weight percentages of C 3 N. The effect of temperature, strain rate, and various defects, including vacancy, crack, and void defects, were also studied in this work. The results of this paper may provide the basis for the emergence of new nanocomposites reinforced with carbon and nitrogen atoms.…”
