| Abstract Scope |
The main disadvantage of Al-Li alloys is an anisotropic behavior combined with limited formability. As conventional processes reach their limits, the formability of Al-Li alloys is to be improved by means of twin-roll casting. Twin-roll casting is an efficient process for the production of thin strips. The characteristic of this process is the combination of solidification and plastic deformation in a single unit. In this study, the twin-roll casting of Al-Li alloy using copper shells was represented by a numerical simulation through a thermofluid model implemented in ANSYS-Fluent. This simulation-based study aims to investigate the influence of casting speed, casting temperature, strip thickness, and length of strip forming zone on strip outlet temperature and a specific length of deformation zone, thus optimizing the practical manufacturing process. The parameters determined by means of the simulation were used for the manufacture of strips and the microstructure was analyzed on their basis. |
