“…Their results showed valuable improvement in the hardness after incorporating SAC content in the Al 5052 alloy. However, Nayak et al 40 added the GS particles in the Al 5052 alloy to enhance the hardness.

In this investigation, an attempt has been made to use the waste material in the fabrication of aluminium-based composite material. Waste spent alumina catalyst (SAC) generated from oil refinery industries has been considered as primary reinforcement particle. Waste grinding sludge (GS) produced from iron forging industry was used as secondary reinforcement material in the preparation of composite. Further, chromium (Cr) has been added to SAC and grinding sludge (GS) reinforced aluminium-based composite material to prevent grain growth as well as to control the grain structure of composite material. Experimental results concluded that by adding 4.5% of GS and SAC with 1.5% Cr in aluminium alloy, mechanical properties such as hardness, compressive strength and tensile strength were significantly improved. Hardness compressive strength and tensile strength was increased by 40.06%, 7.24% and 18.86%, respectively, with respect to the aluminium alloy. However, the reduction in toughness was observed. SEM results depicted uniform distribution of SAC and GS particles in Al/4.5% SAC/4.5% GS/1.5% Cr composite. Thermal expansion behaviour and corrosion weight loss of composite have been also investigated to observe the influence of reinforcement in the aluminium alloy.

“…42 In addition, it is known that the Orowan mechanism is provided by the locking of dislocations in the mechanical properties of MMNCs with the addition of hard particles and it is frequently reported in the literature. [43][44][45][46] The contribution of hard n-Al 2 O 3 particles to deformation hardening during mechanical-milling and the occurrence of grain refinement also explains that the hardness and tensile strength values of MMNCs increases as the amount of Al 2 O 3 increases. The resulting grain refinement and reduction of crystalline size increase the number of grain boundaries and hinder the dislocation movements, which clearly shows the hardening and strengthening mechanism as also stated in the literature.…”

In this study, ZA27-Al2O3-Gr hybrid nanocomposite materials (HNMs) were prepared by powder metallurgy method including mechanical-milling and hot-pressing (HP). The physical and mechanical properties of ZA27-Al2O3-Gr HNMs have been investigated with the primary objective of understanding the influence of the alumina (Al2O3) nanoparticle (n-Al2O3) reinforcement. The density, hardness and tensile strength tests of HNMs carried out to determine the physical and mechanical properties of ZA27-Al2O3-Gr HNMs. Scanning Electron Microscope (SEM) is used for the microstructural evolution of the HNMs. As a result of microstructure examination results, n-Al2O3 were observed around grain boundary while the graphite (Gr) nanoparticles (n-Gr) were dispersed homogeneous throughout ZA27 matrix. Relative density values decreased with the increase of nanoparticle reinforcement ratio from 1%vol to 4%vol., while an increase in porosity values was detected for HNMs. Moreover, the results showed that the addition of n-Al2O3 significantly improved the mechanical properties of the HNMs. Additionally, the HNMs reinforced with 4%vol. n-Al2O3 and 1%vol. n-Gr exhibited the highest tensile strength of about 158 MPa and hardness of 160 HB in comparison with the other HNMs reinforced with different content of n-Al2O3.
