“…The increment in the crystallite size values occurs because of the formation of a 2D CNT channel network on the surface of the Al matrix surface during ball milling, which restricts the radial plastic flow of Al crystallites. Cold welding of particles can, however, continue along the vertical direction and hence, increasing the crystallite size by increasing the CNT content [ 14 , 34 ]. Additionally, the heating rate used as well as the high pressure during SPS consolidation resulted in an enhanced rate of surface diffusion, accelerating the grain growth.…”

“…[ 12 , 13 ]. Moreover, the high-energy ball-milling technique has also demonstrated to be an affordable route to achieve a uniform dispersion, since it is capable to promote an effective interfacial bonding between both phases, while reducing considerable damage in the structure of the reinforcement and thus, preserving their intrinsic properties [ 14 , 15 , 16 , 17 ].…”

“…Several investigations have been reported previously to enhance the understanding and comprehension of Al-CNTs consolidation by varying pressure, temperature and holding time during the SPS process [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. Additionally, it has been reported that faster cooling rates and short processing time during sintering avoid the formation of Al 3 C 4 [ 3 , 14 ]. Efforts have been largely focused on investigating strengthening of the mechanical properties, however, there is also a scientific and industrial interest to address the electrical conductivity properties of monolithic Al-based CNT composites to use them, potentially, as replacement of conductive materials while preserving their enhanced mechanical properties.…”

Spark Plasma Sintering of Aluminum-Based Powders Reinforced with Carbon Nanotubes: Investigation of Electrical Conductivity and Hardness Properties

This paper focuses on reporting results obtained by the spark plasma sintering (SPS) consolidation and characterization of aluminum-based nanocomposites reinforced with concentrations of 0.5 wt%, 1 wt% and 2 wt% of single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs). Experimental characterization performed by SEM shows uniform carbon nanotube (CNT) dispersion as well as carbon clusters located in the grain boundary of the Al matrix. The structural analysis and crystallite size calculation were performed by X-ray diffraction tests, detecting the characteristic CNT diffraction peak only for the composites reinforced with MWCNTs. Furthermore, a considerable increment in the crystallite size value for those Al samples reinforced and sintered with 1 wt% of CNTs was observed. Hardness tests show an improvement in the composite surface hardness of about 11% and 18% for those samples reinforced with 2 wt% of SWNCTs and MWCNTs, respectively. Conductivity measurements show that the Al samples reinforced with 2 wt% of MWCNTs and with 0.5 wt% SWCNTs reach the highest IACS values of 50% and 34%, respectively.

“…An efficient bonding could be established by modifying the wettability angle at the interface. This is usually achieved via the sintering process [24]. The process is depicted in Figure 1 where the particles inserted onto the interfacial boundaries of the welded metal have been shown explicitly.…”

This review is focused on the topical developments in the synthesis of nanocomposites using the simplest top-down approach, mechanochemical milling, and the related aspects of the interfacial interactions. Milling constraints include time duration of milling, ball size, the ball-to-sample content proportion, rotation speed, and energy that took part in a vital part of the structure–property relationships and composite interactions. Milled nanocomposites are being used in different structural applications for their higher performance rate and throughput. The synthesis of different nanocomposites and the effect of various parameters on the mill-ability of nanocomposites are discussed. Moreover, some of the major advancements in the energy sector are discussed in the latter part of the review.

“…It was observed that increasing MWCNT content leads to increase in compressive strength and electrical conductivity of pure Fe. The 3wt.% MWCNT exhibits the best hardness results in comparison with the other contents of MWCNT [11]. Chen et al have examined the compression fracture behaviour of Fe / WC composites [12].…”

In this study, pure Fe and Fe matrix composites (5 wt. % nano-Al2O3, 5 wt. % micron-B4C and 2.5 wt. % nano-Al2O3-2.5 wt. % micron-B4C) were manufactured via powder metallurgy. The density and phase analysis of the produced samples were performed. The electrochemical corrosion behaviour of the samples in a 3.5 wt. % NaCl solution was studied using potentiodynamic polarization at 25, 50 and 75 ºC. The corrosion rate of the samples significantly increased with increasing test temperature. Also, the effect of reinforcement particulates leads to deteriorate corrosion resistance of pure Fe due to the presence of galvanic reactions.
