Abstract

The complete miscibility gap of fcc solid solution has been obtained by thermodynamic calculation in the Al-Zn-Cu ternary system by means of SSOL data. It is clearly indicated that its shape should be connective tunnel space, transforming continuously from Al-Zn side to Al-Cu side, not bell-shaped space as considered previously. Moreover, it has been also shown that there is metastable miscibility gap of fcc solid solution in Al-rich corner of Al-Cu binary system. Its top temperature is about 500 °C and the corresponding composition is around 13.5 at.% Cu.
