An Integrated Computational and Experimental Study of Static Recrystallization in the Mg–Zn–Ca Alloy System

The PRISMS Center is utilizing both experimental studies and simulations to better understand the effect of alloying on static recrystallizationRecrystallization in alloys in the Mg–Zn–Ca system. The kinetics and mechanisms of recrystallization are characterized using electron backscatter diffractionElectron Backscatter Diffraction (EBSD) 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-PlasticityPRISMS-Plasticity framework is employed. PRISMS-Plasticity calculates the dislocationDislocation density distribution within a microstructureMicrostructure after deformation. PRISMS-PF reads both the microstructure and the average dislocationDislocation 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.
