“…They compared the grain structures of low-reduction and high-reduction cold-rolled clad materials and concluded that higher reduction results in fewer coarse elongated grains in the microstructure compared to low reduction. Cha et al [15] studied the interfacial effects of heat treatments on the mechanical properties of the clad material. The EN AW 7075 cladded from both sides with EN AW 6022 has significantly improved strength and elongation after heat treatment because of the activated precipitations and diffusion of major alloying elements in comparison to the as-rolled (bonded) sheet.…”

The present study investigates the accumulative roll bonding process applied to the EN AW 3003 aluminum alloy, serving as a composite material on both sides and consisting of the EN AW 4343 aluminum alloy. For the characterization of the optical microscopy, corrosion tests with saltwater acetic acid and mechanical properties before and after the braze test were employed. The numerical simulations accurately predicted the industrial cold rolling values for the rolling force and surface temperature. The most comprehensive understanding of the cold rolling parameters for both side-cladded materials was achieved by combining predictions for cladded and uncladded materials. The thickness of the cladded layer presented as a percentage after roll bonding was 18.7%. During the cold rolling and annealing, the cladded thickness was increased to 24.7% of the final 0.3 mm of the total cold-rolled product thickness. According to the performed braze test for final thickness, the ultimate tensile strength and yield strength were decreased, and the elongation increased to 18.1%. In addition to the described changes in mechanical properties, the material’s anisotropy improved from 5.4% in the cold-rolled condition to 2.0% after the braze test. After multiple re-meltings of the cladded material, the analyzed chemical compositions allow for recycling and reuse as different 4xxx, 5xxx, and 6xxx alloys.

“…The Al-Zn-Mg-Cu-based AA 7xxx series is widely used in the aircraft and automotive industries for structural materials due to their high strength-to-density ratio [1][2][3]. Although the effects of relatively minor alloying elements such as Fe or Mn upon the microstructures and mechanical properties of these 7xxx aluminum alloys are significant, they are yet to be studied in detail.…”

This study suggests a new way to modify the size and morphology of Al-Fe phases in modified AA 7075 by using an Fe-Mn solid solution powder as the precursor. When Fe and Mn are added in the form of a solid solution, the diffusion of Fe and Mn toward the Al is delayed, thus altering the chemical composition and morphology of the precipitates. The fine, spherical precipitates are found to provide a good balance between strength and ductility compared to the case where Fe and Mn are separately added.

The development of several novel multifunctional components to perform specific unique functions is directed towards meeting the demands for advanced components in industries. In this study, the role played by carbon (Cgr) variation on the steel part composition of cemented tungsten carbide and steel bilayer processed via powder metallurgy was investigated. Microstructural examination through field emission scanning electron microscopy (FE-SEM) and energy dispersive spectroscopy (EDS) revealed the presence of detrimental eta carbide phase (M6C) distributed across the interface of sintered bilayer compacts. A significant reduction of M6C was observed with 0.8 wt.% Cgr when interlayer diffusion was accelerated resulting in better morphology and higher hardness values of 735.70 and 150.97 kgf mm⁻² in WC and Fe layers, respectively. Tensile strength property was evaluated to examine the sintering compatibility and the interfacial bond strength of bilayer specimens. Excellent bond strength was achieved in all sintered bilayer with increasing Cgr level and enhanced densification which consequently improved tensile strength by 19%.
