“…Moreover, metal serrations can be observed at the crack tips of the GNPs/TC4 composites (Figure 9k), which is a clear evidence of ductile fracture [53]. These metal serrations can effectively restrain the opening of the crack and delay the catastrophic fracture of the composites [54][55], which contribute for the simultaneous enhancement of their strength and ductility.…”

“…The nanoparticles on the surface of CNTs and copper-containing compounds are formed, not only to improve the dispersion of CNTs, but also to improve interfacial bonding with a Cu matrix [ 16 ]. When the CNT-reinforced composites are stretched, a stronger interfacial bonding provides higher load transfer efficiency, increasing the tensile strength of the composite [ 17 ].…”

Carbon nanotube (CNT)-reinforced metal matrix composites (MMCs) face the problems of dispersion and interfacial wetting with regard to the matrix. A synergetic method of spray pyrolysis (SP) and flake powder metallurgy (FPM) is used in this paper to improve the dispersibility and interfacial bonding of CNTs in a Cu matrix. The results of the interface characterization show interface oxygen atoms (in the form of Cu2O) and a high density of dislocation areas, which is beneficial for interfacial bonding. The tensile results show that the tensile strength of the SP-CNT-Cu composites is much higher than that of the CNT-Cu composites when the mass fraction of the CNTs does not reach the critical value. This can be explained by the nanoparticles which are found on the surface of the CNTs during the SP process. These nanoparticles not only increase the tensile strength of the SP-CNT-Cu composites but also improve the dispersion of the CNTs in the Cu matrix. Thereby, uniform dispersion of CNTs, interfacial bonding between CNTs and the Cu matrix, and the enhancement of tensile strength are achieved simultaneously by the synergetic method.

Metals and their alloys have been widely used in aerospace, automotive, and chemical industries due to their excellent mechanical properties. [1][2][3] New materials are developed with higher performance to meet more critical working environment. One of the common strategy is to use metal or its alloy as matrix to form metal matrix composites (MMCs) by adding reinforcements such as fibers, whiskers, and particles to achieve optimized performance. [1,4] These reinforcements improve the tensile properties of the alloy, but always sacrifice its plasticity at the same time.Graphene [5,6] is an extraordinary sp 2hybridized nanocarbon material with 2D single-layer structure. Due to its excellent fracture strength (up to %130 GPa), ultrahigh Young's modulus (%1.0 TPa), and high hardness with low density, graphene is considered to be one of the most potential new generation carbon materials in many fields. [7][8][9] In consideration of the complicated fabrication process and the high cost of single-atomic-layer graphene, multilayer graphene nanosheets (GNSs) show wider application potentials. [10][11][12] GNSs have been successfully used to reinforce metallic materials such as aluminum, [13,14] magnesium, [15,16] and copper [17,18] with dramatically improvement of their mechanical properties, such as tensile strength, hardness, and wear behaviors. [19][20][21] Zhou et al. [22] fabricated an aluminum-based composite at 0.4 vol% addition of graphene, and the ultimate tensile strength (UTS) and yield strength (YS) of the composite increased by 33.1% and 32.7%, respectively. Jang et al. [23] produced a 0.5 vol% grapheme-reinforced copper alloy, and around 4 times enhancement of their mechanical properties was achieved. Mu et al. [24] prepared a grapheme-reinforced pure titanium alloy, which exhibited an excellent UTS of þ40% compared to the monolithic alloy.Strengthening by GNSs as an ideal reinforcement material is an important method for improving the mechanical properties of light metallic materials. Compared with the conventional metals, GNSs-reinforced MMCs have extensive applications in many fields due to their excellent properties. Nickel and its alloys have been widely used in gas turbines and aeroengine due to their
