“…Alternative materials can be composites with a metal matrix reinforced with ceramic particles or fibres, the so-called cermets (metal matrix composite-MMC) [18][19][20]. These materials mainly feature a relatively low density (3.95 g/cm 3 for aluminium oxide, approximately 2.7 g/cm 3 for aluminium) and good mechanical properties, such as impact strength, tensile strength, yield strength or elongation [21][22][23].…”

The paper presents the results of studies on the effects of shooting composite materials produced by pressure infiltration with the EN AW-7075 alloy as a matrix and reinforcement in the form of preforms made of α-Al2O3 particles. Composite materials were made with two reinforcement contents (i.e., 30% and 40% vol. of α-Al2O3 particles). The composites produced in the form of 12 mm thick plates were subjected to impact loads from a 7.62 × 39 FMJ M43 projectile fired from a Kalashnikov. The samples of composites with different contents of strengthening particles were subjected to detailed microscopic examination to determine the mechanism of destruction. The effect of a projectile impact on the microstructure of the material within the perforation holes was identified. There were radial cracks found around the puncture holes and brittle fragmentation of the front surfaces of the specimens. The change in the volume of the reinforcement significantly affected the inlet, puncture and outlet diameters. The observations confirmed that brittle cracking dominated the destruction mechanism and the crack propagation front ran mainly in the matrix material and along the boundaries of the α-Al2O3 particles. In turn, numerical tests were conducted to describe the physical phenomena occurring due to the erosion of a projectile hitting a composite casing. They were performed with the use of the ABAQUS program. Based on constitutive models, the material constants developed from the identification of material properties were modelled and the finite element was generated from homogenization in the form of a representative volume element (RVE). The results of microscopic investigations of the destruction mechanism and numerical investigations were combined. The conducted tests and analyses shed light on the application possibilities of aluminium composites reinforced with Al2O3 particles in the construction of add-on-armour protective structures.

“…It was observed that addition of Al2O3 results refined grain size in the composite. From previous reported review [14], it was found that B4C [15], SiC [16][17], and eggshell [18] was reinforced to aluminium alloy to form the composite.…”

The fly-ash produced in thermal power plants is a major pollutant to the air and soil. This paper designs a new composite material with the fly-ash as the reinforcement. For the composite, the AA 6061 aluminum alloy was taken as the matrix, Al2O3 as the primary reinforcement, and fly-ash as the secondary reinforcement. The microstructure and mechanical properties of the proposed composite were measured, and compared with those of previous experiments on AA 6061 alloy. The results show that the proposed composite achieves uniform distribution of Al2O3 and fly-ash in AA 6061 alloy; the mechanical characteristics like tensile strength and hardness were improved after adding Al2O3 and flyash; however, ductility and facture toughness were minimized after the addition. The research findings offer a new way to recycle the fly-ash generated in the thermal power industry.

“…The reinforced particle works as a grain nucleating site inside the solidifying specimen which obstruct the grain growth of the aluminum alloy. Thus, a consistent decrease in grain size with increased reinforcement of uniformly distributed reinforced particles was observed [5]. Secondly, FSP technique leads to intense plastic deformation that neutralizes the pinning effect.…”

This review article investigates the mechanical and tribological properties of metal matrix composites (MMCs) prepared through friction stir processing technique. MMCs are developed materials with enhanced mechanical properties, exhibits their application in automotive and aerospace industries. The limitations of liquid metallurgical route can be reduced by using Friction Stir Processing (FSP) technique. FSP, a developed methodology technologically advanced by friction stir welding process is reviewed to fabricate the MMCs. In FSP, a hole or groove is made in the alloy. Reinforcement filled in the groove or hole are distributed in the matrix material by the FSP tool. Heat produced between the tool and the surface tends to the grain refinement. Owing to grain refinement, mechanical and wear properties of the composites are enhanced. In this review article, mechanical and wear behavior of the composite developed through FSP method are reviewed, which will help the researchers and industrial societies to fabricate the composite of required enhanced properties.
