It has been found that there existed the T phase in the seven alloys. Consequently, it was testified that the T phase was stable at room temperature. At the same time, the phase relationship was not locally right for the isothermal section of 20℃ of Al-Zn-Cu system of the ASM published in 1997. 关键词：AL-ZN-CU 铝合金稳定性 T相 ASM 三元合金
