Abstract Scope |
We investigate the effect of alloying on deformation and recrystallization textures in Mg-Zn-Ca alloys using both experimental characterizations and simulations. Gleeble hot compression samples were subjected to post-deformation annealing. The kinetics and mechanisms of static recrystallization were studied using electron backscatter diffraction as well as dark-field x-ray microscopy (DFXM) + high-energy diffraction microscopy (HEDM). These techniques provide information on the evolution of grain volume, grain orientation, and misorientation within the grains. The in-situ DFXM + HEDM characterization allows individual grains to be tracked throughout static recrystallization, providing valuable information on grain boundary mobility and orientation-dependent growth. In addition, we demonstrate the application of a recently-developed framework that integrates phase-field and Crystal Plasticity Finite Element (CPFE) tools to simulate static recrystallization in Mg-Zn-Ca alloys as well as its effect on the evolution of texture. Future plans include extending the capability of this framework to simulate dynamic recrystallization. |
