| 摘 要： | 为了研究铜铝合金化反应的机理,本文建立了一种基于铜和铝扩散反应进行的有限元模型。由于热传导方程和扩散方程在表达形式上的相似性,所以用模拟热传导的方式来模拟铝在铜电极中的单向扩散过程,以温度分布表示扩散浓度的分布情况。研究表明：若只考虑铝在铜中的单向扩散,将试验中的数据按比例进行换算,这样计算出来的试验结果与模拟结果比较相近。

| Abstract: | A finite element model based on the diffusion reaction of Cu and Al was established to further study the mechanism of Cu and Al alloying.The results show that if one-way diffusion of aluminum in copper is considered exclusively,the calculated results and simulation results are similar according to the proportion of data conversion. |
