“…From the graph, it is observed that, the increasing TiB 2 and CeO 2 particulates content in Al-6061, marginally reduces the ductility in ascast and hot rolled composites [44,45]. When compared to ascast material, it is found that the hot rolled matrix and its MMCs show improved ductility.…”

Development of aluminium composites by stircasting technique is an effective method for fabrication of better quality of MMCs. Stircasting technique is one of the most commonly accepted techniques. In this research work, Al6061 / TiB2+CeO2 hybrid MMCs have been fabricated with varying wt. % of TiB2 (2.5%, 5%, 7.5% and 10%) particulates and constant 5% of CeO2 particulates. The monolithic alloy and hybrid composite were hot-rolled at a temperature of 515°C. Whereas, both the monolithic and hot-rolled hybrid composite was subjected to micro-structural study, hardness and tensile test. Optical microscope analysis revealed uniform dispersal of hard particles with in the base matrix in case of both of ascast and hot-rolled composites. Both ascast and hotrolled hybrid composites have shown extensive enhanced mechanical behavior and high wear resistance when compared with monolithic alloy. Though, ductility of the hybrid MMCs decreased with increasing TiB2 and CeO2 content. A tensile and wear fractography outcome shows the internal fractured structure of a tensile and wear specimen which was analysed using a SEM analysis.

“…However, it was still higher than that of the single-reinforcement composite (Al/B 4 C). In continuation, Chandrashekar et al [ 96 ] also incorporated dual-sized B 4 C powders, namely, 44 µm and 105 µm sizes, in A356 alloy by using the stir-casting method. It was observed that the higher content of B 4 C powders in the dual-particle-size composites will increase their tensile strength and hardness by up to 35% and 15%, respectively.…”

This review article focuses on the aluminum-based metal matrix composites (Al-based MMCs). Studies or investigations of their mechanical and tribological properties performed by researchers worldwide in the past are presented in detail. The processing techniques and applications for Al-based MMCs are also documented here. A brief background on the composite materials, their constituents, and their classification, as well as the different matrix materials and particulates used in Al-based MMCs, can be found in this review. Then, an overview of dual-particle-size reinforced composites, heat treatment of Al alloys, and temper designations used in heat treatment are also included. In addition, the factors influencing the mechanical and wear properties of Al-based MMCs are discussed. The primary objective is that both present and future researchers and investigators will be assisted by the comprehensive knowledge compiled in this article to further explore and work towards the betterment of society in general.

“…Aluminum, due to its non-toxicity, high thermal conductivity, low density, remarkable corrosion resistance, and ease of formation, casting, and machining, finds extensive applications [10][11][12]. The metal's non-sparking and nonmagnetic characteristics, along with being the sixth most ductile and the second most malleable, add to its widespread usage [13].…”

Aluminum alloys are widely recognized as highly advantageous materials for various engineering applications, including pistons, valve components, brakes, engine blocks, and impellers. In this study, our objective was to investigate the mechanical characteristics and surface behavior of the Aluminum alloy (AlSi8Cu3). To achieve this, torsion tests were conducted to analyze the material's response to shear and high deformation, while mitigating instability phenomena. Specifically, torsion tests were performed on annealed aluminum alloy specimens until rupture, at 1/3 of the rupture, and at 2/3 of the rupture to evaluate crucial material properties, such as the modulus of Young and shear modulus. Through these tests, we also examined the hardness of the specimens and analyzed the microstructural state at both the center and periphery of the deformed sections. Additionally, we determined the hardness, microstructure, and values of the strength coefficient (K) and the strain hardening exponent (n) within the plastic domain of the alloy. Our experimental results demonstrated that increasing deformation on the specimens led to a reduction in grain size. Furthermore, this deformation resulted in a decrease in Young's modulus, attributed to the initiation of cavity coalescence. Based on our investigation, we conclude that the obtained results are excellent and hold significant implications for further research in this field.
