“…It is evident that a high density of pores is observed in the as-deposited alloy, and the pore size varies at different positions; the edge of the billet exhibits larger pores than the center region [53]. To achieve a more uniform microstructure and superior performance, densification and further deformation are typically achieved through methods such as hot extrusion, forging, and rolling [54][55][56][57][58][59].…”

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.

A review on the characterization of mechanical, metallurgical, porosity, tribological and corrosion properties of spray deposited Al-alloys are presented in this paper. Al-alloys are potentially used in various applications specifically in bearing materials, aerospace due to low weight to high strength, proper lubrication, excellent wear and corrosion resistance. Al alloys being processed through spray forming technology, which possesses lower processing steps than the other conventional methods like ingot and powder metallurgy. Characterization of Al alloys spray deposits is carried out before and after mechanical processes to know their behaviour. Reviewed the characterization deportment of Al-alloys before and after spray deposition, effect of mechanical process like cold rolling, extrusion, aging, hot rolling, hot extrusion etc. and porosity on the metallurgical, hardness, tensile strength, elongation, tribological and corrosion properties.

“…These structures are characterized by increased strength and at the same time they have low weight and high resistance to various loading levels. The cellular structures are manufactured using mainly the mechanical and electrochemical processing technologies [5][6][7][8][9]. Concerning the manufacturing of these structures, slow deformation at high temperatures with excess gas pressure is one of the most promising technologies.…”

Multi-layer cellular workpieces are used to manufacture fuel tanks, as well as the external hulls of aircraft. These designs are characterized by low weight and high strength. Monotonic formation with inert gases looks promising for the manufacturing of large workpieces. This article presents an approach to the modeling of energy-force parameters during free forming of titanium alloy workpieces in square dies with shortterm creep. The results of mathematical modeling of the investigated process are given in the form of inequations which allow estimating pressure and critical modes. According to these inequations, we found the influence of the process time on blank's relative thickness change in various points of its surface, as well as on its height and maximum damage rate change.
