| Abstract Scope |
Addition of rare earth (RE) elements, such as Y, Ce, Gd, etc., has been used as texture modifiers to improve the formability of Mg alloys. In hot extrusion, the non-RE alloys generally exhibit a {10-10} or {10-10}-{11-20} fiber texture, depending on the recrystallized fraction, whereas the yttrium containing alloys develop weaker texture and a {11-21} fiber component. Recent experiments showed that formation of the {11-20} and {11-21} fiber textures are closely related to continuous dynamic recrystallization (CDRX) of Mg alloys.
In this work, a CDRX model is implemented into the visco-plastic self-consistent (VPSC) framework by quantifying the transformation of low angle boundaries into high angle boundaries inside each grain. Furthermore, a phenomenological multiple slip model is integrated into the polycrystal model for better predictions of the recrystallization texture in the extrusion. The effective multiple slip modes that operate during the dynamic recrystallization are determined through simulation. |
