抄録

A kinetic model based on the principle of maximum degradation rate of the total system free energy, MDR law, using thermodynamic data is applied to (Sn-Zn)/Cu diffusion couples to predict intermetallic compound phases and their order to be formed. According to this model, only γ-Cu₅Zn₈ is predicted to appear when Zn content is less than 10 mass%, while both γ-Cu₅Zn₈ and ε-CuZn₄ can exist with 10 mass%Zn or more, which was in a good agreement with EPMA and TEM observations of Cu plates dipped into Sn-Zn baths. Therefore, it is concluded that the phase prediction based on the MDR law can also be applied to pseudo binary diffusion systems.
