摘　　要：对电子铝箔中添加微量元素实验研究现状进行了总结,概括了高纯铝中的添加微量合金元素的作用机理.其作用机理是微量溶质原子和析出相粒子可提高铝合金强度和再结晶温度、能细化晶粒、对变形织构和再结晶织构的形成都有阻碍作用,通过相变热处理获得析出相强化作用.归纳了富铝端的相反应类型、各相成分和反应温度,提出了高纯电子铝箔的合金元素和加工工艺的优化原则.The present situation of experimental study of electronic aluminum foil doped trace elements is introduced,and the mechanism of doping trace elements in high purity aluminum is summarized. Trace solute atoms and the precipitation phase particles can improve the strength of aluminum alloy,increase the temperature of recrystallization,refine grain,prevent the deformation texture and recrystallization texture formation,and enhance the strength by the precipitation phase in heat treatment. Phase reaction types,phase compositions and reaction temperatures at the rich Al terminal are summarized and the optimization principle of doping elements in high purity electronic aluminum foil and processing technology is proposed.
