Thermal decomposition of nanostructured Aluminum Titanate in an active Al matrix: A novel approach to fabrication of in situ Al/Al2O3–Al3Ti composites

Carbonaceous nanomaterial reinforced Ti-6Al-4V matrix composites: Properties, interfacial structures and strengthening mechanisms

“…Compared to the conventional pure metals (such as Cu, Al, Mg and Ti) and their alloys, metal matrix composites (MMCs) have attracted great interest in recent years owing to their excellent physical/mechanical properties (including high strength and elastic modulus, high hardness, good wear resistance, and good thermal/ electrical properties) [1][2][3][4][5][6][7][8][9][10]. For examples, Cu matrix composites are preferred for electrical and tribological applications owing to their good electrical and thermal conductivities [11][12][13], whereas Al matrix composites are extensively used in aerospace and automotive industries due to their relatively low density and good workability [2,[14][15]. Titanium matrix composites (TiMCs) have also found wide-range applications in aerospace, automobile and chemical industries due to their light weight, high specific strength and excellent corrosion resistance [16][17][18], however, in many applications, their mechanical and physical properties need to be further improved.…”

Mechanical and Thermal Properties of Aluminum Matrix Composites Reinforced by In Situ Al2O3 Nanoparticles Fabricated via Direct Chemical Reaction in Molten Salts

“…The AMMC material dispersion reinforcement is typically achieved by casting or powder metallurgy, with the ceramic particles being introduced ex situ into a solid or liquid matrix. A new AMMC production method has been developed on the basis of the controlled "in-situ" chemical reactions; reinforcing fillers are formed during the chemical interaction between the matrix components and reactive additives [9,12]. Such AMMCs demonstrate excellent mechanical and physical properties, because coherent (i.e., having a standard atomic layer at the interface) or partially coherent interfaces are formed between the matrix and new phases that arise in "in-situ" reactions.…”

“…AMMCs are fabricated both by ex situ synthesis (e.g., liquid ingot casting and powder metallurgy), where reinforcement powder particles are added to the metal melt, and by in situ synthesis (e.g., exothermic dispersion, reactive hot pressing, reactive infiltration, and direct melt reaction), where particles are directly synthesized in the metal melt [6][7][8][9][10][11][12]. The reinforcement in AMMCs can have a form of continuous/discontinuous fibers, whiskers, or particulates.…”

A Review on Traditional Processes and Laser Powder Bed Fusion of Aluminum Alloy Microstructures, Mechanical Properties, Costs, and Applications

“…As global concern for carbon emissions continues to increase, green and low-carbon development has become an important strategy. Aluminum alloy, a lightweight material with high mechanical properties, favorable processing performance, a large reserve, and low price [ 1 , 2 , 3 ], has gradually replaced traditional steel materials and is widely used in aerospace, automotive, construction, and other fields [ 4 , 5 , 6 , 7 , 8 , 9 ]. For example, 7075 and 2024 aluminum alloys are commonly used in the manufacture of skins, structural components, and fasteners in the aerospace industry, and 5052 and 5038 aluminum alloys are commonly used in the manufacture of ships, offshore platforms, and vehicles.…”
