“…Li [ 26 ] investigated the anisotropy of an Al-Zn-Mg-Cu alloy, and they found that {110} <112> brass texture formed during the rolling process contributed to the anisotropic response. Srinivasan et al [ 27 ] examined the equibiaxial tension of an Al-Zn-Mg-Cu alloy. They concluded that the initial brass texture weakens during equibiaxial deformation.…”

Hot compression tests were conducted to explore the deformation behavior of an extruded 7075 aluminum alloy bar at elevated temperatures. Specimens with 0°, 45°, and 90° angles along the extrusion direction were prepared. The compression temperatures were 300 and 400 °C, and the strain rates ranged from 0.001 to 0.1 s−1. The corresponding microstructures were characterized via OM and TEM, and the macroscopic texture was tested using XRD. The results indicated that the strength of the 7075 alloy decreases with higher compression temperatures and is in a proportional relationship with respect to the strain rate. During high-temperature compression, it is easier to stimulate atomic diffusion in the matrix, which can improve thermal activation abilities and facilitate dynamic recovery and dynamic recrystallization. In addition, the coarsening of precipitates also contributed to dynamic softening. When compressed at 300 °C, the stress levels of the 0° specimens ranked first, and those for the 45° specimens were the lowest. When compressed at 400 °C, the flow stresses of the specimens along three directions were comparable. The anisotropic mechanical behavior can be explained by the fiber grains and brass {011} <211> texture component. However, higher temperature deformation leads to recrystallization, which can weaken the anisotropy of mechanical properties.

“…In addition, increasing the range of electric vehicles by reducing the weight of the automobile is an important financial indicator [4,5]. Microstructure, corrosive and mechanical properties of aluminum alloys can be improved by applying aging heat treatments with different cycles, thermo-mechanical methods and retrogression and re-aging (RRA) heat treatment processes [6][7][8][9][10]. Sequence of precipitation of artificially aged 7000 series aluminum alloys; Solid solution (SS) → GP zones → 𝜂 ı → 𝜂(MgZn2)…”

In this study, Charpy impact test specimens were prepared by cutting Al 7075 alloy according to ASTM-E23 standards. The prepared test specimens were dissolved in a single-phase region for 1 hour at 480°C in vacuum atmosphere and artificially aged at 120°C for 24 hours after quenching. After the first step aging heat treatment applied, the specimens were artificially aged for 5-50 hours at 180°C for the second time. Microstructural characterization and fracture surface analyzes of the specimens were determined using SEM (Scanning Electron Microscope) device, crystallographic analysis of the precipitated phases were determined using XRD (X-ray diffraction) device. The increase in the amount of ƞı phase (MgZn2) with increasing double aging heat treatment time was effective in increasing the strength. After 10 hours of double aging heat treatment, the impact toughness value is improved by 300% compared to the single aged condition.
