“…Research on the hightemperature (room temperature to 400 • C) tensile properties of spray-formed 7055-T6 and 7055-T74 alloys by Khan et al [57] indicates that a maximum environmental temperature of 200 • C can be withstood by the structural components of the 7055-T6 alloy. Wang et al [162] found that in the spray-formed Al-8.5Fe-1.1V-1.9Si heat-resistant alloy, the formation of coarse and brittle primary silicon crystals and eutectic phases between dendrites was inhibited due to the low solidification rate, while dispersed fine spherical Al 12 (Fe, V) 3 Si particles with exceptional thermal stability were distributed in the matrix. Such microstructure endows the alloy with excellent room temperature and high-temperature mechanical properties.…”

Spray forming is a manufacturing process that enables the production of high-performance metallic materials with exceptional properties. Due to its rapid solidification nature, spray forming can produce materials that exhibit fine, uniform, and equiaxed microstructures, with low micro-segregation, high solubility, and excellent workability. Al-Zn-Mg-Cu alloys have been widely used in the aerospace field due to their excellent properties, i.e., high strength, low density, and outstanding machinability. The alloy manufactured by spray forming has a combination of better impact properties and higher specific strength, due to its higher cooling rate, higher solute concentration, and lower segregation. In this manuscript, the recent development of spray-formed Al-Zn-Mg-Cu alloys is briefly reviewed. The influence of hot working, i.e., hot extrusion, hot forging, and hot rolling, as well as different heat treatments on the property and microstructure of spray-formed Al-Zn-Mg-Cu alloys is introduced. The second phases and their influence on the microstructure and mechanical properties are summarized. Finally, the potential in high-temperature applications and future prospects of spray-formed aluminum alloys are discussed.

“…AA8009 Aluminum alloy, developed by Skinner et al in 1986(Skinner et al 1986, is regarded as an aluminum alloy applied at a temperature of around 673 K (Zheng et al 2015). Owing to its attractive properties at mid-temperature (Goyal et al 2019;Deng et al 2020), such as high specific strength, ductility, and fracture toughness (Skinner et al 1986;Franck and Hawk 1989), AA8009 alloy has considerable applications in the aerospace and automobile industries to replace Ti alloys (Wang et al 2007;Li et al 2003). Therefore, in recent decades, AA8009 alloy has been widely processed in many different ways, such as mixed solidliquid casting (Sahoo, Sivaramakrishnan, and Chakrabarti 2000), planar flow casting (Yaneva et al 2004), spray deposition (Yan et al 2007), linear friction welding (Koo and Baeslack 1992), and friction stir processing (Nouri, Taghiabadi, and Moazami-Goudarzi 2020) for manufacturing aircraft and aerospace heat resistant components (Gilman et al 1988).…”

The relationship between processing parameters, microstructure, and mechanical properties of Al-8.3Fe-1.3V-1.8Si alloy processed by laser powder bed fusion is seldom studied. Therefore, fully dense alloys with two parameters were selected to investigate this key issue. The results show that the alloy with low power and scanning speed (S200) shows fan-shell-shaped melt pools and laser tracks while another (S350) shows a deeper and wider melt pool. Both alloys obtain a heterogeneous microstructure without a secondary phase in melt pool (MP) and a nano-sized phase in melt pool boundary (MPB). The difference between solid-solution strengthening and Orowan strengthening in MP and MPB contributes to the difference in compressive yield strength (S200: 380 ± 14 MPa and S350: 705 ± 16 MPa), and heterogeneous nano-hardness results in different crack behaviours and failure strains. This work indicates that adjusting processing parameters is an effective method to control microstructure and mechanical properties of this alloy.
