Boundary trend of α1／（α1＋α2 ） phase region at lower Cu side in Al-Zn-Cu system
摘要
The range of miscibility gap above 300 ℃ at low Cu side in Al-Cu-Zn ternary system was obtained by EPMA of 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.
