Abstract Isothermal sections of the phase diagram of the ternary Cu-Fe-Sn system at room temper- ature and 600℃ have been determined by X-ray powder diffraction method,microscopic observation and DTA.Eight single-phase regions:α,β,σ,ε,η,τ,ρ and θ;fourteen two- phase regions:β+η,β+θ,θ+η,θ+ρ,ρ+η,η+ε,ε+τ,τ+ρ,ρ+ε,ρ+α,α+τ,α+ε,ε+σ and α+σ:seven three-phase regions:β+η+θ,θ+η+ρ,ρ+η+ε,ρ+ε+τ,ρ+τ+α,α+τ+ε and α+σ+ε are observed at room temperature.Eight single-phase regions:α,σ,L,ρ′,τ,γ,ξ and ε; fourteen two-phase regions:L+ρ',L+ε,ρ'+ε,ρ'+τ ρ'+α,τ+ε,τ+ξ,τ+γ,ε+ξ,ξ+γ,γ+α,σ+α, γ+σ and τ+α;seven three-phase regions:L+ρ'+ε,ρ'+τ+ε,ρ'+τ+α,ε+τ+ξ,τ+ξ+γ,α+τ+γ and α+γ+σ are observed at 600℃.
