“…Furthermore, it is worth adding that the size of the ceramic reinforcement has an important role in the wear behavior of MMCs. Thus, nanoparticles usually result in higher wear resistance compared with micro-sized particles [ 28 ]. Study of the wear tests showed mass loss values of 1.28, 1.25, and 1.15 mg for AZ-0.2SiC, AZ-0.5SiC, and AZ-1SiC, respectively, and was less than 1.56 mg for AZ31 alloy.…”

Magnesium alloys are attractive for the production of lightweight parts in modern automobile and aerospace industries due to their advanced properties. Their mechanical properties are usually enhanced by the incorporation with reinforcement particles. In the current study, reinforced AZ31 magnesium alloy was fabricated through the addition of bulk Al and the incorporation of SiC nanoparticles using a stir casting process to obtain AZ31-SiC nanocomposites. Scanning electron microscope (SEM) investigations revealed the formation of Mg17Al12 lamellar intermetallic structures and SiC clusters in the nanocomposites. Energy dispersive spectroscopy (EDS) detected the uniform distribution of SiC nanoparticles in the AZ31-SiC nanocomposites. Enhancements in hardness and yield strength (YS) were detected in the fabricated nanocomposites. This behavior was referred to a joint strengthening mechanisms which showed matrix-reinforcement coefficient of thermal expansion (CTE) and elastic modulus mismatches, Orowan strengthening, and load transfer mechanism. The mechanical properties and wear resistance were gradually increased with an increase in SiC content in the nanocomposite. The maximum values were obtained from nanocomposites containing 1 wt% of SiC (AZ31-1SiC). AZ31-1SiC nanocomposite YS and hardness were improved by 27% and 30%, respectively, compared to AZ31 alloy. This nanocomposite also exhibited the highest wear resistance; its wear mass loss and depth of the worn surface decreased by 26% and 15%, respectively, compared to AZ31 alloy.

Electromagnetic stir casting (EMSC) is a highly effective process to produce the metal matrix composite (MMC) because of the uniform mixing of reinforcement with the matrix. The current research is to investigate AA6063-T6/2wt%SiC/5wt%WBP hybrid composite using Microstructure analysis, Field emission scanning electron microscopy (FESEM), X-ray diffraction analysis (XRD), Energy dispersive X-ray spectroscopy (EDS), Tensile strength and Hardness. Stirring time and speed is kept as constant parameter. Microstructure analysis reveals that there is uniform distribution of reinforcement in AA6063-T6 hybrid composite and no voids were observed. FESEM analysis shows that reinforcement have a good bonding with a small porosity. XRD analysis indicates that there are no unwanted contaminants found and Al3Ca shows the highest peak followed by Al2(CO3)3 and CaSiO3. It was concluded that mechanical properties are improved on adding the reinforcement, tensile strength by 22.4% and hardness by 31%.

“…Metal matrix composites (MMCs) acquire considerably better properties, including high mechanical properties, specific modulus, specific strength, damping capacity, and reduced specific wear rate and low density [ 15 , 16 , 17 , 18 ]. The reinforcement used in the metal matrix affects the mechanical strength and durability of the developed material compared to the parent material/unreinforced alloy [ 18 ].…”

The authors researched the physical, metallurgical, and mechanical characteristics of A354 alloy (Al-Si-Mg-Cu) reinforced with 5, 10, and 15 wt% of fly ash metal matrix composites. A baseline alloy and three composites were fabricated by a liquid metallurgy route and poured into a permanent mold to obtain cast rods of dimension Φ32 mm × 156 mm. The metallurgical characterization of the developed alloy and metal matrix composites was conducted using energy-dispersive spectroscopy (EDS), field-emission scanning electron microscopy (FESEM), and X-ray diffraction. All the developed composites showed a pore-free nature, but only A354 alloy reinforced with 5 wt% of fly ash (AF5) possessed a homogeneous distribution and perfect bonding of the fly ash with the A354 matrix. Therefore, transmission electron microscopy (TEM) analysis was performed on the sample AF5. All developed alloys and metal matrix composites were subjected to hardness and mechanical property tests. It was observed that the AF5 sample had 170 ± 5.6 HV and tensile strength of 216 ± 2.3 MPa, 18.8% and 24.8% higher than the A354 matrix, but the ductility (6.5 ± 0.43%) was reduced by 23% from the baseline alloy. Finally, the fractography analysis was conducted on all the samples using FESEM to analyze the fracture mode. The fabricated 5 wt% fly ash-based metal matrix composite showed better mechanical performance than other samples. Hence, sample AF5 is suggested for manufacturing components in automotive and structural parts.
