abstract = {We propose a data-driven strategy for parameter selection
in phase field nucleation models using machine learning and
apply it to oxide nucleation in Fe-Cr alloys. A grand
potential-based phase field model, incorporating Langevin
noise, is employed to simulate oxide nucleation and
benchmarked against the Johnson-Mehl-Avrami-Kolmogorov
model. Three independent parameters in the phase field
simulations (Langevin noise strength, numerical grid
discretization and critical nucleation radius) are
identified as essential for accurately modeling the
nucleation behavior. These parameters serve as input
features for machine learning classification and regression
models. The classification model categorizes nucleation
behavior into three nucleation density regimes, preventing
invalid nucleation attempts in simulations, while the
regression model estimates the appropriate Langevin noise
strength, significantly reducing the need for time-consuming
trial-and-error simulations. This data-driven approach
improves the efficiency of parameter selection in phase
field models and provides a generalizable method for
simulating nucleation-driven microstructural evolution
processes in various materials.},
