“…The use of a very slight fraction of nano particles results in a decent improvement in the performance of the developed composite material. 27,72,75,76 The composite prepared with long fiber or reinforcing elements which have higher surface area proved to be having better structural and functional integrity over micro/nano particles reinforced material. The use of nano wire in the polymer-based composite material is widely used in the process, while in case of MMCs, the dispersion and mixing are prime factors for arrangements of reinforced material in the matrix material.…”

‘The micro/nano reinforced particle’ aluminum metal matrix composites (Al-MMCs) are widely used in manufacturing sector due to light-weight, superior strength-to-weight ratio, better fracture toughness, improved fatigue, and tensile property, enhanced corrosion resistance to harsh environment, etc. This article provides an overview of the manufacturing processes and different reinforcing elements used during the synthesis of Al-MMCs. Generally, the reinforced particles like carbides, nitrides, and compounds of oxides are used. Different organic, inorganic, industrial and agricultural waste which can be used for reinforcement in the aluminum matrix is highlighted with their feasible applications. The common mechanical properties (i.e. hardness, tensile and compressive strength, etc.) reported by different researchers are thoroughly discussed with the aim to highlight the amount of reinforcement and improvement occurred during processing. The formation and methodology for mixing condition and sintering behaviour of Al-MMCs are discussed to impart knowledge about the processing circumstances in powder metallurgical route. The affecting conditions during operating and responsible factor for the tribological behaviour are deliberated in a precise manner to recognize the potentiality of reinforcing particles in Al-MMCs. Finally, the different shortcomings and future prospects of the Al-MMCs are given to encourage the future research directions.

“…These inviting properties make them attractive for a wide variety of applications. Recently, the application of AMMCs has surged in the above-mentioned sectors, which require high AMMCs have been developed using various reinforcements, such as alumina (Al2O3) [15], silicon carbide (SiC) [16], boron nitride (BN) [17], titanium carbide (TiC) [18], silicon nitride (Si3N4) [19], boron carbide (B4C) [20], Al-Cu-Li [21], nitinol (NiTi) [22], aluminum nitride (AlN) [23], zirconium dioxide (ZrO2) [24], cerium dioxide (CeO2) [25], and titanium dioxide (TiO2) [26], that have shown distinctive contributions in enhancing the structural, thermal, damping, mechanical, and corrosion properties of AMMCs [27,28]. However, there are some limitations in choosing the type of preparation method.…”

In this study, Al-BiSn composites were synthesized by a combination of microwave sintering and hot extrusion processes. The structural, morphological, mechanical, and thermal properties were investigated to elucidate the role of Bi60Sn40 (BiSn) alloy content (5, 10, and 15 wt.%) in modifying the properties of Al-BiSn composites. The X-ray diffraction (XRD) patterns confirmed the presence of aluminum and BiSn particles. Distribution of BiSn particles in Al-BiSn composites was confirmed by field emission scanning electron microscopy associated with energy dispersive X-ray analysis (FE-SEM-EDX). Results indicated that hot extruded Al-(15 wt.% BiSn) composite exhibits maximum hardness (78 ± 4 Hv) and tensile strength (185 ± 3 MPa), which were 117% and 58% improvements, respectively, compared to pure Al. This improvement in mechanical properties can be attributed to the strengthening effect of BiSn particles. A decline in the values of the coefficient of thermal expansion (CTE) with an increasing amount of BiSn particles reflects the enhanced thermal stability of developed Al-BiSn composites. The promising properties of Al-BiSn composites make them suitable for many industrial applications.

“…On the other hand, the C element, which is transformed into Al 4 C 3 during the as cast and extrusion process, significantly improve mechanical properties such as yield strength, tensile strength, and Young's modulus [21]. Lastly, CeO 2 addition greatly increase the hardness, tensile strength, yield strength, and ductility of composites in the as-cast condition [22,23].…”

In the present work, nanocomposites-based 3XXX series Al alloy with three different types of hard nanoparticles, including TiO2, C, and CeO2, were produced employing two techniques such as mechanical milling and stir-casting method in order to evaluate the viability of integration of the reinforcement in the Al matrix. The integration and dispersion capability of the reinforcement into the Al alloy (3xxx Series) matrix was evaluated, using a phase angle difference and surface roughness analyses by atomic force microscopy operated in both the contact mode (CM-AFM) and tapping mode (TM-AFM), respectively. The distribution profile of both rugosity and the phase angle shift was used to statically quantify the integration and dispersion of the reinforcement into the extruded samples, by using the root mean square (RMS) parameter and phase shift coupled with the events number (EN) parameter. Results from Atomic Force Microscopy (AFM) analyses were corroborated by X-ray diffractometry and scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Microhardness tests were conducted to identify the mechanical properties of the composites in the extruded condition and their correlation with the microstructure. A close relationship was found between the microstructure obtained from the AFM and X-ray diffractometry (XRD) analyses and mechanical properties. Among all, the C reinforcement produced the major changes in the microstructure as well as the best integration and dispersion into the Al-alloy coupled with the best mechanical properties.
