“…Typically, 2000 series aluminium alloys are among the commonly used aluminium alloys in the WAAM process [13][14][15] due to the characteristics of high specific strength, light weight and excellent heat resistance [16,17]. Typical alloys of 2219, 2024, 2324 and 2524 were widely used in high temperature resistant parts of aerospace [18][19][20][21][22][23][24][25]. The mechanical properties of Al-Cu alloys fabricated by WAAM have always been the focus of attention, and relevant researches mainly focus on printing parameters and heat treatment.…”

The microstructure, mechanical properties and their anisotropies of wire-arc additive manufactured Al–Cu alloy at two different printing speeds were investigated, and post heat treatment is optimised. The results show that the grains are finer and the fraction of primary second phase is lower in the alloy prepared at the faster printing speed. The aging hardening response of the solution-treated sample is significantly faster than that of the direct-aging sample, and the peak hardness is higher. The mechanical properties of the as-deposited and T6-treated alloy both show anisotropy, and the latter one is more significant. The anisotropies are mainly attributed to the high porosity in inter-layer of the samples, and these pores are more significant for the T6-treated samples.

“…High-strength aluminum alloys have been widely used to fabricate large transition rings in carrier rockets due to their high specific strength, high specific stiffness, and outstanding mechanical properties at high and low temperatures [ 1 , 2 , 3 , 4 , 5 ]. Compared to a conventional Al-Cu-Mn series alloy, the Al-Zn-Mg-Cu series alloy exhibits higher strength as a potential material for large transition rings.…”

Thermomechanical treatment is an effective way to refine the coarse microstructures of aluminum alloys. In this work, multiaxial forging deformation at high, medium, and cryogenic temperatures (i.e., 450, 250, and −180 °C, respectively) was performed on 7085 Al–Zn–Mg–Cu alloys, and its effect on the microstructure evolution and mechanical properties during the subsequent T6 heat treatment process was studied. The results revealed that the coarse particles were broken into finer particles when deformed at cryogenic temperatures, promoting the dissolution of the material after solid solution treatment. Dynamic recrystallization occurred when deformed at 450 °C; however, more dislocations and substructures were found in the samples deformed at 250 and −180 °C, causing static recrystallization after solid solution treatment. The cryogenic deformed sample exhibited a more intense and homogeneous precipitation phase distribution. The strength of the sample deformed at high temperature was high, but its elongation was low, while the strength of the sample deformed at medium temperature was low. The microstructure refinement of the cryogenic deformed sample led to high comprehensive mechanical properties, with an ultimate tensile strength of 535 MPa, a yield strength of 506 MPa, and a fracture elongation of 11.1%.
