Grain size evolution

The calculation takes into account the influence of temperature on the coefficients of the model as well as the cyclic recrystallization. The module can perform end-to-end calculations of microstructure evolution in the process chain with inheritance of calculation results and works for both 2D and 3D problems. The kinetics of recrystallization is described by the Johnson-Mehl-Avrami-Kolmogorov (JMAK) equation.

Both processor and postprocessor regimes of microstructure simulation are available in QForm. The results of the calculation are shown in the workpiece fields. The following parameters are calculated: volume fraction and average grain size for dynamic, static, and metadynamics recrystallization, total recrystallized volume fraction, average grain size, ASTM grain number, microstructure evolution type, retained strain, critical deformation, initial grain size before each recrystallization cycle, the number of completed recrystallizations when cyclic recrystallization calculation is enabled, as well as reference fields: deformation time, average temperature and strain rate during deformation, dwell time and grain growth time.▲
