摘要：

Partial isothermal sections of the Cu-rich corner of ternary Al-Cu-Zn system at 200 and 240 degrees C were plotted up to 55 at.% Cu and 85 at.% Zn based on scanning electron microscopy, energy-dispersive x-ray spectroscopy and x-ray diffractometry analyses of ten ternary alloys. Seven phases were observed at both isothermal temperatures, and no new ternary phases were found. The results were compared with previously published works, and the gamma-phase was confirmed to exist as two phases: gamma Cu9Al4 and gamma Cu5Zn8.
