摘要：
An algorithm is developed for simulation of phase transitions in the solid state. The algorithm permits the derivation of the corresponding kinetic curves for different initial conditions (quantity and configuration of new-phase nuclei, distance between the closest nuclei). The results of simulation are analyzed by means of the Johnson–Mehl–Avrami–Kolmogorov equation and the logistical function for determining the corresponding coefficients. Analogies are established between the results of simulation and the experimental kinetics of isothermal transformation of austenite in alloy steel. © 2018, Allerton Press, Inc.
