Abstract
The study of the phase equilibria of the Fe-Mn-Zn system is of great significance for understanding color hot-dip galvanizing. In this work, the phase equilibria of the Fe-Mn-Zn system at 600°C were investigated through 30 alloys and 6 diffusion couples. Based on the results obtained, the isothermal section of the Fe-Mn-Zn system at 600°C was proposed. Only the ε phase was found, while the ε1 and ε2 phases reported in the literature were not found. Three ternary compounds, Γ′, τ1, and τ2 phases, exist at 600°C, among which τ1 and τ2 phases were newly discovered in this work. The crystal structures of the τ1 phase were also determined.
