For the growth of intermediate phase layers formed in a poly-phase diffusion zone, the equation in which the rate constants of phase growth are expressed as functions of the interdiffusion coefficients and the boundary concentrations of each phase was derived by modifying Heumann's method.The purpose of this study was to elucidate the factors controlling the layer growth of intermediate phases phenomenologically.The simulation by using the above equation show that the relative magnitude of the rate constant of phase growth in a poly-phase diffusion zone was related to the relative values of D×ΔC in each phase. It is also concluded that the rate constant of the total width of a diffusion zone is controlled by the value of nΣi=1(Di×ΔCi). Therefore if the value of D×ΔC in each phase is known, the total width of a diffusion zone could be quantitatively predicted.
