Enhanced tensile, hardness and wear behaviors of pure aluminum matrix reinforced with steel chips via powder metallurgy technique

Applicability of metallic reinforcements for mechanical performance enhancement in metal matrix composites: a review

“…Also, refinement in composite matrix grain size with increase in the volume fraction of the Cu powder was linked to the improved mechanical performance observed in the Cu powder reinforced A356 composites produced. Emara (2017) compared the mechanical properties of powder metallurgy processed unreinforced aluminium, aluminium matrix composites reinforced with 5, 7.5 and 10 wt.% steel machining chips (SMC), and those reinforced with 5 and 10 wt.% SiC. It was observed that the per cent porosity in the steel chip reinforced composites was lower than that for the SiC reinforced composites.…”

“…Thus, they are now considered ahead of conventional metallic alloys in several applications spanning sports and recreation, building and civil structures, electrical, electronics and computer systems, security and surveillance, industrial thermal facilities, and transportation (Miracle, 2005;Vasanth Kumar, Keshavamurthy, Perugu, Koppad, & Alipour, 2018). Some metallic alloys which have been utilized as metal matrices for MMCs are aluminium, magnesium, titanium, zinc and copper (Emara, 2017;Hassan & Gupta, 2002a). Conventionally, these metal matrices are reinforced with ceramic materials, among which are aluminium oxide (Al 2 O 3 ), silicon carbide (SiC), titanium oxide (TiO 2 ), graphite (C) and boron carbide (B 4 C) (Ramnath et al, 2014;Salih, Ou, Wei, & Sun, 2019).…”

“…The concerns regarding the limitations of ceramic reinforced MMCs have attained new heights, particularly since MMCs are now deployed as structural and stress-bearing materials in a number of high-tech applications, where structural integrity and safety are crucial service demands. This background is instructive in understanding the motivation for the extensive studies already reported in finding alternative means to enhance properties and functionality of MMCs (El-Labban et al, 2016;Emara, 2017;Hassan & Gupta, 2002a;Thakur, Kong, & Gupta, 2007).…”

Steel Chips Reinforcement in Aluminum-Based Composites: Revolutionizing Manufacturing via Stir Casting Technique

“…Comprising primarily aluminum with other elements like copper, zinc, magnesium, and silicon, these alloys offer a remarkable blend of strength, lightweight nature, corrosion resistance, and malleability [2]. The precise composition and processing techniques allow engineers to tailor their properties to specific applications, making them indispensable in aerospace, automotive, construction, and consumer goods sectors [3].One of the most notable features of aluminum alloys is their outstanding strength-to-weight ratio, making them ideal for applications where lightweight materials with high structural integrity are essential [4][5]. Additionally, aluminum alloys exhibit excellent corrosion resistance, especially when combined with certain alloying elements, ensuring longevity and durability in various environments [6].Furthermore, the malleability of aluminum alloys facilitates intricate shaping and forming processes, enabling the production of complex components with relative ease.…”
