摘要：
A mathematical model is proposed for diffusion; it takes into account the appearance and disappearance of phases in the diffusion zone during isothermal processes. Time integration is performed using the Crank–Nicholson scheme for solving finite-difference equations, and space coordinate integration is performed by the finite element method. The adequacy of the proposed mathematical model is supported by calculation examples. © 2015, Pleiades Publishing, Ltd.
