The phase constitutes and phase compositions in the eight alloys designed with different compositions of Al-Zn-Cu system have been determined after the homogenous
treatment and then equilibrium cooling to 20±C by use of optical microscope, electron
probe microanalysis and X-ray di®raction. It has been found that there existed the T0
phase in the seven alloys. Consequently, it was testified that the T0 phase was stable
at room temperature. At the same time, the phase relationship was not locally right
for the isothermal section of 20±C of Al-Zn-Cu system of the ASM published in 1997.
