“…and all these excellent properties make graphene an ideal reinforcing material to fabricate the aluminium or its alloy matrix nanocomposites [83]. Graphene reinforced aluminium matrix nanocomposites with enhanced strength, stiffness, good ductility and wear resistance are widely studied by researchers [84][85][86][87][88][89]. Grain refinement due to the presence of graphene, high hardness, high strength and graphene's self-lubricating character are the reasons for these improvements [15].…”

“…Further, the wear resistance of the nanocomposite materials has been improved significantly due to the formation of protective transfer layer in the composite, which inhibits cracks generation and propagation. The proposed wear resistance was micro cutting abrasion [85]. The transfer layer has significant contribution on friction and wear behaviour of the material.…”

“…Aluminum matrix composites have attracted the attention of many researchers due to their advantages of low cost, low density, high specific strength, high ductility, and excellent processability. The reinforcements added to the traditional aluminum matrix composites are typically categorized into particles (such as SiC [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ], Al 2 O 3 [ 8 , 9 ], B 4 C [ 10 , 11 ], TiC [ 12 , 13 ], graphite [ 14 , 15 ], diamond [ 16 , 17 ], graphene [ 18 , 19 ], and others), whiskers [ 20 , 21 ], fibers [ 22 , 23 ], and nanomaterials [ 24 ]. Among these options, particle reinforcement plays a predominant role in improving the dimensional stability of composites.…”

Negative thermal expansion (NTE) ceramics Sm0.85Zn0.15MnO3 (SZMO) and ZrMgMo3O12 (ZMMO) were selected to prepare Sm0.85Zn0.15MnO3-ZrMgMo3O12/Al-20Si (SZMO-ZMMO/Al-20Si) composites using ball milling and vacuum heating-press sintering processes in this study. The synergistic effect of the SZMO and ZMMO NTE ceramic reinforcements on the microstructure, mechanical properties, and coefficient of thermal expansion (CTE) of the composites was investigated. The results show that the processes of ball milling and sintering did not induce the decomposition of SZMO or ZMMO NTE ceramic reinforcements, nor did they promote a reaction between the Al-20Si matrix and SZMO or ZMMO NTE ceramic reinforcements. However, the excessive addition of SZMO and ZMMO NTE ceramics led to their aggregation within the composite. Adding a small amount of SZMO in combination with ZMMO effectively increased hardness and yield strength while reducing CTE in the Al-20Si alloy. The improvement in strength was primarily provided by SZMO, while the inhibition effect on CTE was primarily provided by ZMMO. An evaluation parameter denoted as α was proposed to evaluate the synergy effects of SZMO and ZMMO NTE ceramic reinforcements on the mechanical properties and CTE of the composites. Based on this parameter, among all composites fabricated, adding 2.5 vol% SZMO NTE ceramic and 10 vol% ZMMO NTE ceramic resulted in an optimal balance between CTE and strength for these composites with a compressive yield strength of 349.72 MPa and a CTE of 12.55 × 10−6/K, representing a significant increase in yield strength by 79.20% compared to that of Al-20Si alloy along with a notable reduction in CTE by 26.44%.

“…Graphene, a new two-dimensional material, has much higher physical and mechanical properties than traditional materials [7]. As an ideal reinforced material, it has been proved that graphene can greatly improve the properties of composites [8]. The Al-graphene composite material has high specific strength, excellent ductility, and good mechanical properties, and its properties are significantly improved compared to the traditional Al matrix composite material.…”

Effects of Defects and Doping on an Al Atom Adsorbed on Graphene: A First-Principles Investigation

et al. 2020

View full text Add to dashboard Cite

In order to enhance the interaction between an Al atom and graphene in graphene-reinforced aluminum-based composites, the method of first-principles calculation was used to investigate the adsorption behavior of Al atoms on graphene. Our calculations indicate that defective and doped graphene are energetically favored for Al atom adsorption compared with pristine graphene. The adsorption effects show that both defects and doping can improve the stability of the Al–graphene system. Furthermore, it was also found that defects and doping lead to a red-shift of the highest optical absorption peaks. The results of the investigation provide a theoretical basis for the future application of graphene-reinforced aluminum-based composites in optical and optoelectronic devices.
