“…Stir casting lies under the category of liquid-phase processing technique used for the production of AMCs and consists of mixing of preheated dispersoids in the vortex of matrix melt with the help of ultrasonic probe or mechanical stirrer followed by pouring and solidification in the predefined moulds. [2,181,182] This technique has been recognized as the most commonly adopted processing method for AMCs as it provides superior applicability to mass production with easier control and handling, greater cost effectiveness, and almost net shaping. [55,115] The major steps involved in this technique are shown in the process chart, refer Figure 18.…”

Aluminum metallic composites (AMCs) have been recognized as promising material exhibiting excellent functional and structural properties that can be significantly tailored to meet the industrial demands as well as to meet the design criteria for many applications such as aerospace, automobiles, marine, defense, and so on. Herein, an effort is made to provide an extensive overview of the various processing techniques adopted for the development of AMCs. Various processing kinetics of stir casting technique are elaborated comprehensively in terms of existing challenges, conceivable modifications incorporated in it. Considering the critical assessment on mechanical properties made through various kinds of literature, an electromagnetic stir-squeeze casting synergically equipped with ultrasonic transducing probe and bottom pouring attachments is recommended as the most appropriate processing technique for the development of AMCs. Moreover, appropriate recommendations regarding process variables and additives/modifiers, and potential future research opportunities are also addressed significantly to encourage the ongoing and upcoming researchers, which lead this critical Review toward novelty and uniqueness.

Global requirement for minimum cost, high efficiency, and good grade materials has made a diversion in research from base alloys to composite materials, since the last five decades. In the case of metal matrix composites, aluminium metal matrix composites have been certified and steadily advanced due to properties such as high strength, low density, and high wear resistance. They are widely used in automobile industry, aircraft industry, structural applications, and many other defence systems. Researchers have observed that the addition of nano-size SiC NP reinforcements to aluminiumbased matrix yields superior properties and good bonding characteristics between matrix and reinforcements of nanocomposites. Along with silicon carbide particulate primary nano-reinforcements, researchers studied the properties of aluminium metal matrix nanocomposites with the addition of secondary reinforcements. These hybrid nanocomposites exhibited improved wear resistance. This article reviews the fabrication methods, mechanical properties, and tribological properties of aluminium-based hybrid metal matrix nanocomposites.

“…Nanoparticles with a large contact angle with the matrix is difficult to be incorporated and dispersed in the melt. In addition, friction stir processing [14,15], numerical modeling [16,17] and discontinuous ultrasonic treatment [18] were attempted for enhanced distributions of nanoparticles in material matrix. The interaction between nanoparticles and the solidification front was also investigated [19][20][21].…”

To reduce the cost of nanocomposites and improve the dispersion of nanoparticles, Al2O3np/SiCnp/Al hybrid nanocomposites are fabricated by combining liquid-state blowing and ultrasonic-assisted casting. The average grain size of the matrix decreases to 39 μm in Al2O3np/SiCnp/Al, which shows improvements of approximately 118% and 26% as compared to those of Al2O3np/Al and SiCnp/Al, respectively. X-ray Diffractometer (XRD) results confirm the presence of SiCnp and Al2O3np in hybrid nanocomposites. The dispersed SiCnp and Al2O3np are homogeneously distributed in the matrix and no clusters consisting of SiCnp and Al2O3np exist in the microstructure. Theoretical analyses also verify that there is little possibility for clusters to form in the melt. Good bonding between nanoparticles and Al is demonstrated. Neither cavities nor reaction products exist at the interface. The ductility and the strength of Al2O3np/SiCnp/Al are improved. The improvement in yield strength of Al2O3np/SiCnp/Al, in comparison with that of A356, is about 45%.
