“…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.

A Critical Review on Synthesis of Aluminum Metallic Composites through Stir Casting: Challenges and Opportunities

2020

Aluminum metallic composites (AMCs) have been recognized as promising material exhibiting excellent functional and structural properties that can be significantly tailored to meet the industrial demands as well as to meet the design criteria for many applications such as aerospace, automobiles, marine, defense, and so on. Herein, an effort is made to provide an extensive overview of the various processing techniques adopted for the development of AMCs. Various processing kinetics of stir casting technique are elaborated comprehensively in terms of existing challenges, conceivable modifications incorporated in it. Considering the critical assessment on mechanical properties made through various kinds of literature, an electromagnetic stir-squeeze casting synergically equipped with ultrasonic transducing probe and bottom pouring attachments is recommended as the most appropriate processing technique for the development of AMCs. Moreover, appropriate recommendations regarding process variables and additives/modifiers, and potential future research opportunities are also addressed significantly to encourage the ongoing and upcoming researchers, which lead this critical Review toward novelty and uniqueness.

“…The proper choice of the reinforcement material in terms of shape, sizes, and chemical stability plays a vital role during the performance. 2,10,14 Utilization of carbon-based nano material can be seen in Al-based material for the substantial increment in the hardness and tensile strength of the material. 15,16 However, the processing and commercialization of the carbon-based material limit the industrial applicability to greater extent due to huge investment.…”

The study focuses on the microstructural, phase transformation, and physical and mechanical aspects of aluminum/zinc oxide composite produced by a hybrid microwave sintering technique. In the present case, zinc oxide nanorods were synthesized through a cost-effective thermal decomposition method. The obtained zinc oxide nanorods’ length was in the range of 76–168 nm observed through high-resolution transmission electron microscopy images and crystallinity nature was confirmed by the bright spot in the selected area electron diffraction pattern. Two different wt% (i.e. 0.5 and 2) of zinc oxide nanorods were utilized for the fabrication of the composite material. The diffraction pattern of the milled powder and energy dispersive spectroscopy results shows effective diffusion of zinc oxide nanorods in the aluminum. The elemental mapping of milled powder illustrates the uniform distribution of the reinforcement over matrix material. The micro-hardness results exhibit a higher hardness of 27.78% with a small fraction of 2 wt%. The nano-indentation results confirm the improvement in the nano-hardness by 32.21% with 2 wt% of zinc oxide with a marginal decrease in elastic modulus by 4.92%.
