摘　　要：对稀土量不同的Ａｌ－Ｚｎ－Ｍｇ合金的第二相进行了测量与研究，给出了合金中第二相状态随稀土量变化的规律．结果表明，第二相明显影响合金的超塑性．The second phase of Al--Zn--Mg alloy with different rare earth components was carefully measured, calculated and analyzed. The results show that the state of the second phase of the alloy was changed regularly with the increase of rare earth components, but it kept in the steady state when the strain was increased; the second phase influences not only the grain structure of the basic body,but also the superplasticity.

关 键 词：第二相状态 稀土元素 铝合金 超塑变形
