“…The reinforcement of ceramic materials such as B 4 C and SiC to the Al matrix in MMCs provides low density, improved hardness, high strength, and good tribological properties. [9][10][11] MMC's can be produced by two production methods: liquid-state and solid-state methods, including infiltration and in situ manufacturing methods. Among all production methods, the powder metallurgy method has been reported to offer a more homogeneous structure and economical conditions.…”

In the presented study, aluminum metal matrix nanocomposites reinforced with SiC and B4C, with different reinforcement ratios (0–4 wt%), have been prepared using the powder metallurgy method. The main objective of this study is to investigate the effect of different reinforcements and reinforcement amounts on the machinability of metal matrix nanocomposites using different machining processes (WEDM and CNC milling). The surface morphologies of the samples were investigated before and after machining using scanning electron microscopy and chemical analysis of the samples was obtained using EDX and X-ray diffraction. The surface hardness, roughness, and metal removal rate (MRR) before and after machining were examined to investigate the effect of the machining process on the surfaces of the samples. According to the results of the study, the hardness value of the nanocomposite containing 4% B4C by weight (195.6 HB) increased by approximately 90% compared to the hardness value of the pure Al2024 alloy (101.6 HB). After both machining processes, the hardness values of all nanocomposites decreased. In addition, the tensile strength values of the nanocomposites containing 2% B4C and SiC by weight are 392.8 MPa and 377.7 MPa, respectively, while the tensile strength value of the pure Al2024 alloy is 201.7 MPa. After both machining processes, the hardness values of all nanocomposite samples decreased. While the MRR values decreased with the increase in the reinforcement amount of the nanocomposites after machining, the SR values decreased.

“…Fracture toughness and ductility are the important parameters for any material as it prevents a material from failure and these properties are very important for shock load applications. 18 Ceramic particles such as B 4 C, SiC, Al 2 O 3 , TiC, MgO and SiO 2 are the commonly used reinforcement phase in MMCs. Superior properties of these materials such as high compressive strength, high hardness, higher wear resistance and refractoriness make them suitable choice as reinforcement materials in MMCs.…”

The aim of the present study is to investigate the effect of Si and SiC addition on the microstructure, mechanical, and corrosion properties of Al matrix-based composites. Al–Si (2 wt% fixed) alloy reinforced SiC composites were prepared by stir-casting process using SiC reinforcement contents from 0 to 20 wt% at an interval of 5%. A uniform dispersion of SiC particles in the Al matrix was observed from the scanning electron microscopic analysis. Maximum hardness is found for composites having 15 wt% reinforcement content. Pin-on-disc wear test reveals that SiC particles increase the wear resistance of composites. Corrosion test reveals that composites reinforced with 20% reinforcement content shows the minimum i corr among all the compositions, attributing to the maximum corrosion resistance. Tribological and corrosion behaviour were found to be dependent on the reinforcement content. However, they were not interdependent on each other. It is expected that the present study would be helpful in the development of lightweight composites for aerospace and shipping industries applications.
