Abstract The evolution of crystallographic texture during the thermo-mechanical processing of aluminium sheet is accompanied by the development of plastic anisotropy and, most notably, the well-known earing phenomenon. In the present paper we analyse the formation of texture and earing properties in sheets of the Al-Mg alloy AA 5050A (ISO AlMg1.5(D)) along a process route resulting in temper H16 after cold rolling and temper H44 after lacquering. This process route, which is characterized by interannealing in combination with a mild final temper rolling pass, was established for the production of Al packaging sheet with medium strength and very good earing properties. Besides a detailed characterization of the development of microstructure, texture and resultant earing properties during standard processing, measures to improve the earing properties by adapting the ratio of the relevant rolling and recrystallization texture components are addressed.

回火轧制以控制 AA 5050A 铝合金的纹理和耳孔

摘要 铝板热机械加工过程中晶体织构的演变伴随着塑性各向异性的发展，尤其是众所周知的耳化现象。在本文中，我们分析了铝镁合金 AA 5050A (ISO AlMg1.5(D)) 板材的织构和耳塞性能的形成，其工艺路线导致冷轧后回火 H16，涂漆后回火 H44。这种工艺路线的特点是结合温和的最终回火轧制道次，用于生产具有中等强度和非常好的耳形性能的铝包装板。除了对标准加工过程中微观结构、质地和所得耳塞特性的发展进行详细表征外，
