“…Moreover, regarding texture evolution in EN AW-5182, Figure 6a-j shows good agreement between laboratory and industrial sheets. Figure 6a-d highlight the strong development of β-fiber texture components, most prominently the S and Brass orientations [5,58,59]. Additionally, the comparison of the intensities in the pole figures for laboratory and industry indicates fewer rolling structures in laboratory processing.…”

“…The various possible strength levels, together with high fracture toughness and good corrosion resistance, open a wide field of applications [3]. Over the last decades, the influence of crystal orientation on the mechanical properties and on the forming ability of the Al-components has been intensively investigated and has recently gained eminent interest with the rising importance of Al-sheet materials for automotive applications [5][6][7].…”

“…Major influences on Cube texture are given by the degree of cold-rolling and annealing temperatures as well as solute elements [33]. However, especially in EN AW-5182, the Mg in solid solution can readily reduce the dominance of the cube texture by influencing the dislocation cell formation, especially at lower strains [5,34].…”

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.

Determination of plastic strain ratio (r, also known as the Lankford coefficient) from texture data is one of the most widely used applications of crystal plasticity methods. Early attempts using Taylor theory and x-ray texture data already provided practically useful information of e.g. drawability of sheet metals. Developments in recent decades within both electron backscatter diffraction and computational mechanics have significantly improved the accuracy of these calculations. Predictions can now be made that compares relatively well with experiments making r-value predictions from texture data a routine method within material and process development. The current work reviews recent studies on plastic strain ratio determination by computational means for aluminium sheet metal, with the aim to assess the expected accuracy using modern crystal plasticity methods. Furthermore, we investigate the major sources of error in these calculations by comparison between previous studies and with new experiments and calculations. In particular, we observe and investigate a maximum in the absolute error occurring typically at 45° to the rolling direction. The sources of this error are discussed in terms of both model conditions and the material heterogeneities giving rise to anisotropy.

The metallic components are manufactured through several thermomechanical processes. Each selected procedure has multiple targets. The first target is to obtain the required dimensional criteria and second, to achieve the ideal mechanical response toward the application. This is currently accomplished through years of knowhow combined with an academic background of materials science and engineering. Since metals are polycrystalline materials, the several rotations of the crystals, the preferred orientation also known as texture, and their interactions, are crucial characteristics that are directly correlated to the final response of the material, and one could apprehend its thermomechanical prehistory as well as predict is behavior. Different atomic arrangements act differently texture-wise therefore in the current review article, the evolution of the microstructure and the crystallographic texture through the thermomechanically rolling process especially of Al alloys for packaging applications is analyzed. The crystallographic texture evolution in 3xxx Al alloys in different processing routes is presented and compared to the anisotropic effects occurring during deep drawing. The earing phenomena in Al alloys are correlated to the produced texture and therefore their understanding is crucial in order to highlight the importance of texture control throughout the thermomechanical process.
