Crystallographic Texture Evolution of Aluminum Alloy 3104 in the Drawn and Wall Ironing (DWI) Process

Aluminum beverage cans should have very specific crystallographic textures to increase productivity, reduce losses and reduce the amount of material. The present work seeks to add information on the crystallographic texture of aluminum alloy 3104 H-19 during the different manufacturing steps, which undergoes a flat sheet of metal for a cylindrical body. The work scope encompasses from the cup drawing to the final ironing operation and its objective is to add information on the texture evolution of the aluminum alloy undergoes in the intermediary steps. Crystallographic texture continues to change from the drawn cup through the ironing stages. This rotation is assumed to be a grain alignment with the plastic flow of the material.

铝制饮料罐需具备特定的晶体学织构（crystallographic texture），以提升生产效率、降低损耗并减少材料使用量。本研究旨在补充3104-H19铝合金在不同制造工序中的晶体学织构相关信息，这些工序需将金属平板加工为圆柱形罐体。本研究的覆盖范围从杯形拉深工序延伸至最终的变薄拉深工序，研究目标是补充该铝合金在中间工序中的织构演变相关信息。晶体学织构在拉深杯体至变薄拉深各阶段中持续发生变化，这种织构旋转被认为是晶粒随材料塑性流动发生取向调整的结果。
