“…There is a clear endothermic peak at temperature 476.7 ºC. It has been discussed by Liu et al [29] as well as by He et al [30] that the peak corresponds to the melting of α-Al matrix and η-MgZn 2 , which implies that the start melting temperature (T m ) of the alloy ingot is 476.7 ºC. Considering the accuracy of furnace, the temperatures ranging from 460 ºC to 480 ºC were selected in this paper.…”

“…Furthermore, Chen et al [20] found that the higher Cu content leads to higher quench sensitivity in Al-Zn-Mg-Cu alloys with the same content of Zn, Mg, and other trace elements. Moreover, the effect of alloying elements on the quench sensitivity, microstructure and mechanical properties of 7085 aluminum alloy has been deeply investigated [21][22][23][24]. However, only the effect of a single alloying element or Zn/Mg ratio on the quench sensitivity of 7085 aluminum alloy has been studied and reported.…”

The quench sensitivity of 7085 aluminum alloy with different contents of the main alloying elements (Zn, Mg and Cu) was investigated using time-temperature-transformation (TTT) curves and end quenching experiments. Then, the quenching microstructure was analyzed using transmission electron microscopy. With increasing the contents of the main alloying elements, the transitions and nose temperatures of the TTT curves are obviously increased, while the incubation time of 0.5% η (MgZn2) phase precipitation content is decreased. In addition, as the contents of the main alloying elements decrease, the conductivity of the quenched samples is increased, but the hardness of the quenched samples is decreased. Moreover, the size and area fraction of the η phase are increased with increasing the contents of the main alloying elements. Based on the experimental results, the increase of Mg and Cu contents can decrease the stability of supersaturated solid solution and increase the lattice distortion energy, which can increase the quench sensitivity of 7085 aluminum alloy.

“…AA7085 alloy is widely used in the aeronautical and aerospace industries because of its high strength, good toughness and slow quench sensitivity. 13) With the rapid development and wide application of large slabs, understanding the restoration behavior becomes important from an industrial perspective. In addition, the recrystallization behavior of a deformed AA7085 alloy is different from that of the other 7000 series aluminum alloys.…”

Effect of Heating Rate on Microstructure, Texture and Tensile Properties of AA7085

The microstructure, texture and tensile properties of a deformed AA7085 alloy during solution treatment were investigated in the temperature range of 350 to 500°C with heating rates of 1 and 600°C/min. The results show that the alloy sheet solution treated with rapid heating rate exhibits a finer grain structure and narrower grain size distribution compared to the alloy sheet solution treated with slow heating rate, indicating that driving force is more important than sub-boundaries coalescence and mobility during rapid heating process. Heating rate affects the qualitative recrystallization textures, whereas it has no significant changes on the quantitative texture of the individual components. After two-stage ageing, the samples with low heating have slightly higher tensile properties than those with high heating rate.
