| Abstract Scope |
The PRISMS center is utilizing both experimental studies and simulations to better understand the effect of alloying on static recrystallization in alloys in the Mg-Zn-Ca system. The kinetics and mechanisms of recrystallization are characterized using electron backscatter diffraction on annealed Gleeble plane-strain compression samples. This data is used to inform the computational models. In order to simulate alloying effects on static recrystallization, a sequentially integrated PRISMS-PF/PRISMS-Plasticity framework is employed. PRISMS-Plasticity calculates the dislocation density distribution within a microstructure after deformation. PRISMS-PF reads both the microstructure and the average dislocation density per grain as inputs and then computes the evolution of recrystallized grains by taking into account the differences in stored energy between grains. This capability can be used to predict the volume fraction and distribution of recrystallized grains as a function of time which will be compared to an experimentally determined Johnson-Mehl-Avrami-Kolmogorov (JMAK) relationship. |
