Abstract Scope |
We develop an approach to model the kinetics of recrystallization in metals starting from the deformation-induced dislocation microstructure with the phase-field framework. Specifically, we model the evolution of subgrain boundaries with the initial microstructure gleaned from the EBSD technique for deformed aluminum. The phase field model employed here considers the grain boundary energy and width of the boundary based on the misorientation angle through the model parameters. In addition, we parametrically studied the effect of stored elastic energy within the subgrains on the kinetics of recrystallization making this study a first of its kind. We defined an additional elastic energy in the subgrains as a function of their size, wherein the accumulated elastic energy within the subgrains is inversely proportional to the size. By resolving the subgrain structure, the presented algorithm paves the way for developing predictive kinetic models that fully account for the deformed state of recrystallizing metals. |
