Abstract: The range of miscibility gap above 300℃at low Cu side in Al-Cu-Zn ternary system was obtained by EPMAof the designed alloys and diffusion-couples treated for equilibrium. The results about the boundary trend of the α₁/(α₁+α₂) phase region was obtained. The α₁/(α₁+α₂) boundary moves towards the lower Zn side with the increase of Cu content. The results are opposite to traditional phase diagrams obtained by experiments, but consistent with recent thermodynamic calculations.
