Abstract:We carry out an extensive comparison between Johnson-Mehl-Avrami-Kolmogorov (JMAK) theory of firstorder phase transformation kinetics and phase-field (PF) results of a benchmark problem on nucleation. To address the stochasticity of the problem, several hundreds of simulations are performed to establish a comprehensive, statistically-significant analysis of the coincidences and discrepancies between PF and JMAK transformation kinetics. We find that PF predictions are in excellent agreement with both classical … Show more
