“…These suggest that the potential 60°<1, 1, 1> twin relation between Goss and P may indeed promote the mutual transformation in between, which also conform the principle of low‐free energy in twin grain. Such potential evolutional mechanism may provide the possible explanation of the aforesaid co‐occurrences of P and Goss in reference 27 and an indirect indicator to observe the nucleation in recrystallization by PSN, which has been reported to affect the fatigue resistance 34 …”

“…Such phenomenon can be also observed in the nonisothermal annealing of other aluminium alloys. [23][24][25][26] Recently, Saeed suggests that the concurrent precipitation, which is related to P, also promotes the Goss texture in as-forged Al-Cu-Mg. 27 These above suggest that there might be an unknown potential evolutional mechanism between P and Goss.…”

Continuous texture evolution of the Al‐Cu‐Mg alloy during the staged solid solution and corresponding influence on fatigue property has been studied by means of X‐ray diffraction, electron back scattered diffraction and scanning electron microscopy. The characteristic texture transition rate XCGB and orientation streamline approach was introduced to further investigate the behind mechanisms. The results show that the two‐step solid solution could significantly enhance the XCGB, thereby contributes to reduce the fatigue crack growth rate of Al‐Cu‐Mg T3 sheet during stage Π. The near Cube texture with high Schmid factor (SF) and low Taylor factor (TF) tends to induce significant crack deflection, crack closure and strengthened planar slip. The potential 60°<1, −1, 1> twin relation and mutual transformation existed between Goss and P texture would further reduce the fine random orientation grain and inter‐granular fatigue crack extension. Such above effects would be responsible for the excellent correspondence between XCGB and fatigue resistance.

“…Under this case, recovery and precipitation before recrystallization can accelerate recrystallization. 19,20) The early nucleation sites will consume gradually deformation matrix, resulting in a coarse elongated grain structure. Continuous recrystallization seem to become more significant due to sub-grain growth and coalescence ( Fig.…”

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.

“…Research has shown that MAF of AA7075 Al alloy at 200 °C results in formation of Goss and cube texture components from the initial copper texture component [26]. Additionally, Moghanaki et al reported the formation of Copper and Brass texture components during MAF processing of AA2024 alloy [27]. A classical study by Zhou et al [28] on the stability of textures in FCC materials states that during plastic deformation, the grains rotate and tend to reach a stable end position.…”

Lightweight 3rd generation Al-Cu-Li alloy AA2050 was severely deformed via Multi Axial Forging (MAF) at 170C followed by artificial aging at 150C. Effect of MAF and post MAF aging on microstructure and precipitation was investigated using transmission electron microscopy (TEM). Formation of deformation bands and large dislocation cells were evident on MAF processed samples. Post MAF peak aging resulted in the distribution of fine T1 precipitates in grain interiors with reduction in grain boundary precipitation. Bulk texture studies reveal the formation of strong Goss and S texture components upon MAF processing. Further, low temperature artificial aging doesn’t exhibit significant changes in texture characteristics, either in terms of texture intensities or texture components. Polarization studies showed that peak aged samples exhibited better corrosion resistance compared to un-aged samples. Overall, 12 pass MAF processed and peak aged samples showed higher corrosion resistance. Further, corrosion surface morphologies examination revealed the change in corrosion mechanisms with thermomechanical treatments. Improved corrosion resistance after MAF and peak aging widens the requirements in aerospace and aircraft applications for such engineering alloys
