“…ElmaCast technology provides cast billet cooling rates comparable to those of RS/PM technology (over 1000 K/s for billet diameters up to 14 mm). It was also successfully tested in industrial conditions for experimental aluminum alloys, in particular with additives of rare earth metals [ 14 , 15 ], namely iron, calcium, and zirconium [ 16 , 17 ]. This suggests that the application of the EMC method to high-strength wrought aluminum alloys based on the Al–Zn–Mg system with a high Fe content is promising.…”

Aluminum alloys are one of the most common structural materials. To improve the mechanical properties, an alloy of the Al–Zn–Mg–Ca–Fe system was proposed. In this alloy, when Fe and Ca are added, compact particles of the Al10CaFe2 compound are formed, which significantly reduces the negative effect of Fe on the mechanical properties. Because of the high solidification rate (about 600 K/s) during cylindrical ingot (~33 mm) production, the electromagnetic casting method (ECM) makes it possible to obtain a highly dispersed structure in the cast state. The size of the dendritic cell is ~7 μm, while the entire amount of Fe is bound into eutectic inclusions of the Al10CaFe2 phase with an average size of less than 3 μm. In this study, the effect of radial shear rolling (RSR) on the formation of the structure and hardening of the Al–8%Zn–3.3%Mg–0.8%Ca–1.1%Fe alloy obtained by EMC was studied. Computer simulation of the RSR process made it possible to analyze the temperature and stress–strain state of the alloy and to select the optimal rolling modes. It was shown that the flow features during RSR and the severe shear strains near the surface of the rod (10 mm) provided a refining and decrease in the size of the initial Fe-containing particles.

“…The demand for high-performance light alloy wires has shown a surge for various engineering applications, such as load-bearing slings, metallic mesh, welding wire, wire-based additive manufacturing [1][2][3][4]. The traditional method of preparing metallic wire consists of a series of complicated steps, including casting [5], extrusion [6], rolling [7], drawing [8], and annealing [9], which require repeated cycles among these steps. Besides, the lengthy traditional processes are almost ineffective in quickly selecting alloy compositions for high performance metallic wires.…”

“…However, with the rapid development of aerospace technology and transportation, the service temperature of Al alloys being the high-temperature structural components in engine blocks, cylinder heads, and engine room components is becoming harsher and harsher [7,8]. For example, the temperature of the Al alloy for its application as a missile shell can reach 400 • C (0.6 T m ) or above during the operation in question [9]. In high-temperature conditions, the mechanical degradation of Al alloys has become a key constraint to their application [10].…”

To ensure that Al alloys are being served as the high-temperature structural components for applications in aerospace and transportation, it is necessary to investigate their high-temperature mechanical behavior and failure mechanism. In this paper, the mechanical behavior of the as-extruded Al-5Zn-2Mg-0.3Cu (in wt.%) alloy was studied and compared under different high-temperature tensile-testing conditions. It was found that the yield strength and the ultimate tensile strength of the alloy gradually decreased with the increase in temperature, but its elongation ratio showed a slightly increasing trend. Failure analysis demonstrated that there were a lot of ductile dimples on the fracture surfaces and that obvious necking occurred for the samples being tensile-tested at different temperatures. Surface observation revealed that the initiation of micro-cracks was mainly attributed to the self-cracking of the brittle phase particles. Moreover, when the testing temperature was between 450 °C and 550 °C, micro-cracks could also occur at the interface between phase particles and the Al matrix.
