Aluminium slugs are semi-finished products, often in the form of metal disks, that are used to produce various supplies like aerosol cans and components for motor vehicles. Ball technologies d'Aluminium Avancées Canada produce slugs by punching metal strips that are cast and rolled in-house. They have been having difficulties with the production of slugs with a large thickness to diameter ratio (t/d). For ratios approaching 1/1, defects are present on the outer diameter of the slugs, making them inappropriate for further processing. In an effort to understand how the tooling parameters influence the occurrence of defects, microstructural characterization of slugs made with 2 different sets of tooling will be done, and simulations of the process will be performed. The models will be calibrated using tensile and shear tests results, and validated with experiments. They will then be used to study the influence of the tooling parameters on the quality of the slugs.

铝弹是半成品，通常是金属圆盘的形式，用于生产各种供应品，如喷雾罐和机动车辆部件。加拿大Avancées铝球技术公司通过冲压内部铸造和轧制的金属带材来生产弹丸。他们在生产大厚度直径比(t/d)的弹状物方面一直存在困难。对于接近1/1的比例，段塞的外径存在缺陷，不适合进一步处理。为了了解模具参数如何影响缺陷的发生，将对用2套不同刀具制造的弹状物进行微观结构表征，并对过程进行模拟。模型将使用拉伸和剪切测试结果进行校准，并通过实验进行验证。然后，它们将被用来研究模具参数对弹状物质量的影响。
