摘 要：<正> As a part of the systematic investigationon phase relationships of Zn-Al based alloyscontaining Cu and/or Si, the equilibrium phasetransformations of the quaternary Zn-Al-Cu-Sisystem at 285℃ were investigated by using X-raydiffracti on, scanning electron microscopy andelectron probe microanalysis techniques. A five-phase of （α+β+εT’+σ） and a four-phase of （β+ε+η+σ） were detected separatelycoexisting in the Zn-Al-Cu-Si system at 285℃.Then the 285℃ isothermal section of Zn-Al-Cu-Sisystem （with 0.1% -Si content） was established,and an equilibrium reaction was determined at286℃ as the following pattern, β+T’=α+ε
