“…General minor intensities of the recrystallization texture components, including Cube orientation, suggest randomization of texture to a certain degree (especially in the laboratory alloy). Concerning the strengthening of the Q component during recrystallization, the sometimes-stated origin near to shear bands (reported in some Mg-containing heavily-rolled Al-alloys) could not be verified due to the absence of attendant microstructural features and the rarely emerging Goss component, which can also indicate features of shear during deformation [6,11,37,60]. As the entire texture development does not show any influence of PSN, a minor significance of microstructural changes based on coarse particles can be assumed; however, a more detailed analysis of the primary and secondary phase distribution will nevertheless be the subject of future investigations.…”

With the rising importance of aluminum sheets for automotive applications, the influence of microstructure and texture on mechanical properties and on forming behavior has gained re-increased interest in recent years. This paper provides an introduction to the topic and demonstrates the evolution of microstructure and texture in the standard alloys EN AW-5182 and EN AW-6016 for different processing scales. Moreover, strategies for texture and microstructure characterization of automotive Al-sheets are discussed. As the development of alloys or processes usually starts in laboratory facilities, the transferability to the industrial scale of the results thereof is studied. A detailed analysis of the entire processing chain shows good conformity of careful laboratory production with the industrial production concerning microstructure as well as qualitative and quantitative texture evolution for EN AW-5182. While comparable grain sizes can be achieved in final annealed sheets of EN AW-6016, quantitative discrepancies in texture occur between the different production scales for some sample states. The results are discussed in light of the basics of plasticity and recrystallisation including the effect of solutes, primary phases, and secondary phases in the alloys.

“…Oriented nucleation (ON) and oriented growth (OG) can affect the formation of recrystallization texture. 25) The orientation map of the deformed alloy after annealing at 375°C shows profuse cube oriented grains (Fig. 10).…”

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.
