Abstract:
An approach based on the method of the free-energy density functional for calculating the nucleation rate of the second-phase precipitates has been developed. The nucleation rate, as well as the characteristics of the critical nucleate, are calculated directly from the modeling results of evolution of the concentration field obtained by solving the deterministic or stochastic Kahn–Hilliard equation.
Keywords:
nucleation rate, free energy density functional method, Cahn–Hilliard equation, binary alloys.
