Evaluation of the microstructure of in-situ reaction processed Al3Ti-Al2O3-Al composite

Proper matrix-reinforcement bonding in cast metal matrix composites as a factor of their good quality

“…Al 4 C 3 formed between the components (the phenomenon is described in the works [11, [13][14][15][16][17][18][19]. Table 2 presents examples of the reactivity of selected materials used as reinforcement for metal composites with selected matrix metals.…”

“…These materials have to meet certain standard requirements [12, [14][15][16] and the best practice is to purchase them from solid recognized manufacturers. Otherwise the finished products, composite materials, may have a variety of defects, such as different sizes of reinforcement elements, or impurities in the casting structure.…”

“…The process of infiltrating the reinforcement with liquid metal has been widely discussed in the works [11][12][13][14][15][16][17][18][19]. The bonding of reinforcing structure with the matrix sometimes faces serious problems, especially at too low or too high infiltration pressure [1,2].…”

Fabrication of Al matrix composite reinforced with submicrometer-sized Al2O3 particles formed by combustion reaction between HEMM Al and V2O5 composite particles during sintering

“…AMCs with high strength, high hardness, high-specific elastic modulus, etc., are being widely used in the aerospace and automobile industries. Recently, many AMCs have been produced by in-situ combustion reaction processes [7][8][9]. In the present study, HEMM and the sintering process are employed to fabricate Al-V matrix composite reinforced with submicron-sized Al 2 O 3 and Al x V y (Al 3 V, Al 10 V) phases.…”

Enhanced precipitation hardening in an alumina reinforced Al–Cu alloy matrix composite

“…Thus, mechanical properties of the in situ products are usually superior to those made by reinforcement-matrix mixing [6]. One commonly adopted in situ method involves the displacement reaction between Al and selected metal oxides, such as NiO [7], TiO 2 [8], MoO 3 [9], Fe 2 O 3 [10], CuO [11] and ZnO [12]. In many of these systems, Al 2 O 3 reinforcements in various physical forms are produced.…”
