“…Density of a MMC depends on many factors such as shape and size of the particle, nature of reinforcement and percentage composition. 17 The density and hardness of the specimens containing varied amount of reinforcements are shown in Figure 3. It was observed that the density of the composites decreased with increase in reinforcement percentage.…”

“…This drop in density upon increase in the amount of reinforcement comes to term with the fact that the ceramic particles are volatile and extremely hard as compared to the matrix material which generally is a pure metal. [15][16][17][18] However, in case of deformation there is a definite increase in density and hardness due to strain hardening. 19 The aforementioned attributes of the prepared material have been analysed in order to discern the abilities of the prepared material from the pure metal in achieving the desired properties.…”

The aim of the present study is to investigate the structural, wear and thermal behaviour of Cu–Al2O3–graphite hybrid metal matrix composites. Copper matrix composites with Al2O3–graphite reinforcement (0.5-0.5, 1.0-1.0, 1.5-1.5 and 2.0-2.0 wt%) were prepared by stir casting process. Phase, microstructure, density, hardness, wear, compressive strength and specific heat of prepared samples have been investigated. X-ray diffraction revealed that there is no intermediate phase formation between matrix and reinforcement phase as a result of interfacial bonding between them. Microstructure study shows the uniform distribution of Al2O3–graphite particles in the Cu-matrix. Density and hardness were found to decrease with increase in reinforcements percentage whereas the compressive strength was found to increase as the amount of reinforcements was increased. Composite containing 2.0 wt% reinforcements showed the maximum resistance to wear. Specific heat was found to increase with addition of reinforcements; however, this increase was very marginal. Structural, wear and thermal properties of these Cu matrix-based hybrid metal matrix composites were found to be dependent on the reinforcements concentration. It is expected that the present composite will be useful for heat exchanger and heat sink applications.

“…It was found that dispersion of reinforcement is uniform and hardness increases whereas density decreases with the increased weight percentage of reinforcement. 25 Sohag et al investigated the effect of reinforcement on microstructural and mechanical behaviour of Al-Cu alloy. It is found that reinforcement distributed uniformly in Al-Cu alloy.…”

The present paper reports the effect of aluminium oxide and titanium oxide reinforcement on the properties of aluminium matrix. Aluminium matrix reinforced with aluminium oxide–titanium oxide (2.5, 5.0, 7.5 and 10 wt.%) in equal proportion were prepared by stir casting. Phase, microstructure, energy dispersive spectroscopy, density, hardness, impact strength and tensile strength of prepared samples have been investigated. X-ray diffraction reports the intermediate phase formation between the matrix and reinforcement phases due to interfacial bonding between them. Scanning electron microscopy shows that aluminium matrix has uniform distribution of reinforcement particle i.e. aluminium oxide and titanium oxide. Density of composite decreases due to variation of reinforcement and it shows low density after preheating. Hardness decreases due to the amalgamation of reinforcements. Impact strength was found to increase with the addition of reinforcements. Hybrid composite of aluminium matrix and (5% aluminium oxide + 5% titanium oxide) reinforcements have maximum engineering and true ultimate tensile strength. It is expected that the present hybrid metal matrix composites will be useful for aircraft rivets.

“…The wear resistance and strength of the hybrid reinforcements are much higher than for aluminum [8]. Properties of the composite mostly depend on reinforcement weight percentage, chemical reaction with matrix, the grain size of reinforcement, and the production method [9]. Hybrid aluminum metal matrix composites can be fabricated through infiltration, powder metallurgy, squeeze casting, semi-solid, and stir casting [10].…”

Hybrid reinforcement’s novel composite (Al-Fe3O4-SiC) via powder metallurgy method was successfully fabricated. In this study, the aim was to define the influence of SiC-Fe3O4 nanoparticles on microstructure, mechanical, tribology, and corrosion properties of the composite. Various researchers confirmed that aluminum matrix composite (AMC) is an excellent multifunctional lightweight material with remarkable properties. However, to improve the wear resistance in high-performance tribological application, hardening and developing corrosion resistance was needed; thus, an optimized hybrid reinforcement of particulates (SiC-Fe3O4) into an aluminum matrix was explored. Based on obtained results, the density and hardness were 2.69 g/cm3, 91 HV for Al-30Fe3O4-20SiC, after the sintering process. Coefficient of friction (COF) was decreased after adding Fe3O4 and SiC hybrid composite in tribology behaviors, and the lowest COF was 0.412 for Al-30Fe3O4-20SiC. The corrosion protection efficiency increased from 88.07%, 90.91%, and 99.83% for Al-30Fe3O4, Al-15Fe3O4-30SiC, and Al-30Fe3O4-20SiC samples, respectively. Hence, the addition of this reinforcement (Al-Fe3O4-SiC) to the composite shows a positive outcome toward corrosion resistance (lower corrosion rate), in order to increase the durability and life span of material during operation. The accomplished results indicated that, by increasing the weight percentage of SiC-Fe3O4, it had improved the mechanical properties, tribology, and corrosion resistance in aluminum matrix. After comparing all samples, we then selected Al-30Fe3O4-20SiC as an optimized composite.
