Carbon nanotubes (CNTs)-reinforced Al composites have attracted attention due to their high specific strength and low density, which makes them suitable for the use in aerospace and automobile industries. In this review, preparation methods of Al/CNTs composites for achieving a homogeneous desperation of the CNT in the Al matrix are summarized. In addition, the effect of processing methods on carbon nanotube distribution and enhancement of mechanical properties such as toughness, wear behavior and hardness of the nanocomposites are reviewed. Improvement of mechanical characteristics was observed by the incorporation of carbon nanotubes into aluminum matrix. The strengthening factors gained by the carbon nanotubes addition are the interface of metal and CNTs and the chemical and structural stability of CNTs.

“…Composite materials are defined as two or more components that are chemically distinct and their interfaces are clearly separated. The matrix can be either metals, ceramics, or polymers [8][9][10][11]. The compos-ite materials show high strength and stiffness [14,15].…”

“…This method, as a solid-state and non-equilibrium technique, is capable of producing a wide range of microstructures containing nano-crystalline supersaturated solid solutions, quasi-crystalline intermediates and amorphous phases [15,20,21,24]. Also, in contrast to other new techniques such as liquid quenching (or melt-spinning), the MA process is a controllable process and operates at low temperatures as well as having the capability of large scale production [25][26][27][28][29][30].…”

In this study, nanostructured (Fe 85 Ni 15) 100-x Cu x (x = 0, 0.5, 1.5, 3 and 5) powders were synthesized via mechanical alloying process. The obtained phases, microstructure, and magnetic properties of these alloys were studied by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), and vibration sample magnetometer (VSM). XRD results indicated that after a suitable time of milling, Ni and Cu were homogeneously distributed in the Fe matrix, and (bcc) α-(Fe(Ni-Cu)) solid solution was obtained. It was found that by increasing Cu content in the alloy, work hardening increased, and thus the size of grains decreased while the internal micro-strain increased. Also, morphological observations indicated that the addition of Cu led to the formation of finer particles. Also, VSM analysis showed that the addition of Cu into Fe-Ni alloys lowered Ms. On the other hand, the coercivity increased by increasing copper content up to 1.5 at. %.

“…Therefore, depending on the type of application, contact materials should be optimized to provide reliability, long contact life and low cost [6]. Much work has been done towards producing and evaluating the electrical performances of contact materials [6][7][8][9][10][11][12][13][14][15][16][17][18].…”

In this study, the effect of polyethylene glycol on the particle size and morphology of Cu25W composite powder was investigated. For this purpose, commercial elemental copper and tungsten powders were milled in a planetary-type ball mill. Milling conditions, namely ball-to-powder weight ratio and milling speed, were selected to be 10:1 and 300 rpm, respectively. In order to avoid agglomeration and to decrease the tendency of cold welding among powder particles, polyethylene glycol at the amount of 2 wt% was used as a process control agent. Morphological evolution of milled powders was investigated using scanning electron microscopy. In addition, the variation of particle size as a function of milling duration was examined using laser diffraction analysis. It was found that powder particle size gradually decreased with increasing milling duration. However, compared to the powder mixture without the process control agent, the powder mixture containing polyethylene glycol tends to lower the milling duration to achieve the same amount of particle size reduction. As a result of this effort, the usage of polyethylene glycol as a process control agent was found to be effective to obtain a composite powder with smaller particle sizes, especially in the earlier stages of milling process.
