“…One such kind of composite is the metal matrix composite (MMC), in which the metal constitutes the matrix and required reinforcements are added to the matrix to enhance the essential properties of the composite [2]. Because of the enhanced properties of MMCs compared with their pristine form, they have a wide range of applications in varied industries, such as marine vessels [3], structural engineering [4], manufacturing of engineering goods [5], machining industries [6], automobiles [7], aerospace [8], etc. From this, it is clear that MMCs are widely useful in applications wherein sturdy mechanical properties constitute the major requirement.…”

The present investigation aimed to determine the optimal parameters for wire-cut electrical discharge machining (WEDM) for stir cast aluminum alloy AA6063 at 850°C reinforced with 10 wt.% green SiC (SiC g ) and black SiC (SiC b ) particles. The WEDM machining parameters, such as pulse on time (TON ), wire feed (WF) rate, and flushing pressure (FP) of the resultant stir cast AA6063/SiC b and AA6063/SiC g composites, were optimized using the Taguchi method with L9 orthogonal array to estimate the responses, such as surface roughness and metal removal rate. Further, through grey relational analysis, the finest parameters for WEDM of AA6063/SiC b and AA6063/SiC g composites were evaluated as TON = 50 μs, WF rate = 18 m/min, and FP = 3 MPa. With the optimum parameters obtained, conformational experiments were conducted, and the scanning electron microscopic images were recorded, along with the energy-dispersive X-ray (EDX) spectroscopic data of the worn surfaces and debris. From the EDX mapping images of the machined surface, it was evident that AA6063/SiC b displays a more polished surface than AA6063/SiC g . However, for applications requiring a high metal removal rate, AA6063/SiC g displays better results than AA6063/SiC b .

“…From ANOVA, the contribution of feed per tooth and nose radius to the surface roughness was 89.97%, whereas the contribution of cutting depth and cutting velocity was only 10.03%. Choudhary et al [15][16] prepared samples of 2, 4, 6, and 8 wt% with 400 mesh SiC reinforcement using stir casting technique. Then the impact strength, hardness, tensile strength, and other mechanical properties were tested.…”

In this paper, the finite element cutting simulation model with irregular distribution of multiple particles is established, the stress and strain distribution of SiC particles in the process of machining, as well as the material removal mechanism are analyzed. The effects of cutting velocity and feed per tooth on the surface quality of the material are also analyzed. The effect of feed per tooth on subsurface damage is revealed. The results show that in the micro-milling of SiCp/Al2024 composites, the particle removal form is mainly crushing and extraction. The surface defects of the workpiece mainly include pits, scratches, cracks, and extrusion damage. When the cutting velocity increases, the surface defects gradually change to crack, which can improve the surface quality of the workpiece. Increasing the feed per tooth will increase the surface defects of the workpiece and lead to poor surface quality. When the feed per tooth increased from 0.428 µm to 0.714 µm, the subsurface damage thickness increased from 35.2 µm to 47.3 µm.

“…According to the formation of the composites, we can group them into in-situ [1] and ex-situ composites [2]. The reinforcement could be graphite [3], graphene [4][5][6][7][8][9], carbon nanotubes [10][11][12][13], ceramics [14][15][16][17], metallic nano-sized particles [18][19][20] or fibers, whereas the matrix materials could be aluminum [21,22], magnesium [23], steel [24], copper [25], etc.…”

The paper reviews the preparation of the different metallic nanocomposites. In the preparation of composites, especially in the case of nanocomposites, interfacial phenomena play an important role. This review summarizes the literature on various interfacial phenomena, such as wettability and reactivity in the case of casting techniques and colloidal behavior in the case of electrochemical and electroless methods. The main contribution of this work lies in the evaluation of collected interfacial phenomena and difficulties in the production of metal matrix composites, for both nano-sized and micro-sized reinforcements. This study can guide the composite maker in choosing the best criteria for producing metal matrix composites, which means a real interface with good adhesion between the matrix and the reinforcement. This criterion results in desirable mechanical and physical properties and homogenous dispersion of the reinforcement in the matrix.
