Recent researches of the bio-inspired nano-carbon reinforced metal matrix composites

Effect of process parameters on microstructures and properties of Al–42Si alloy fabricated by selective laser melting

“…However, when the energy density is 35.8J/mm 3 , the hardness of the alloy is obviously higher, because the selective laser melting is a process of rapid heating and cooling, and has the effect of fine grain strengthening and the size of primary Si particles. According to the Orowan reinforcement equation [ 37 , 38 ]: Where d p is the average particle size; M is the average orientation factor; b is the bergheit vector of alloy; G m is the shear modulus of alloy; ν is Poisson's ratio; λ is the particle spacing. Therefore, the larger the Si particle size, the higher the strength.…”

The Wear Performance of Cu-Based Composites Reinforced with Boron Nitride Nanosheets

“…They still served as a lubricator. However, their agglomeration makes the adjacent Cu particles easily peeled off by the sliding ball [ 38 ]. This means that, in 0.8-CMC, the aiding effects of BNNSs were weakened by the adverse effects of their agglomeration.…”

Mechanical and electrochemical behaviors assessments of Aluminum- Graphene Oxide composites fabricated by mechanical milling and repetitive upsetting extrusion

“…These findings are due to inconsistency of bonding in GO and Al which composed of covalent and metallic bonds, respectively [34]. This covalent-metallic interface has a high interfacial energy, and as a result, GO nanoplates tend to form ag-glomerates throughout the metal matrix [35]. For this reason, in previous reported works [23,35] applied no more than 2 wt.…”

“…This covalent-metallic interface has a high interfacial energy, and as a result, GO nanoplates tend to form ag-glomerates throughout the metal matrix [35]. For this reason, in previous reported works [23,35] applied no more than 2 wt. % of GO in order to avoid agglomeration formation and improve the mechanical properties of matrix.…”
