| 摘 要： | 采用铆钉法制备了Al／Cu／Mg三元扩散偶，在真空炉进行扩散反应，利用SEM背散射电子像和微区电子探针分析，研究了扩散反应层的特征。在450℃下，Al／Cu／Mg三元扩散偶的三元交界处生成了五个三元化合物：Al6CuMg4，Al7Cu3Mg6，Al2CuMg，Al5Cu6Mg2和Cu5Al3。

| Abstract: | The diffusion-reaction zones of Al/Cu/Mg diffusion couples made by inlaying method were researched to identify their characteric by means of back-scattered electron images of Scanning electron microscope and Electrion microprobe analysis. The results indicate that sintering temperature plays a prime role in the development of the number of phase layers. Five ternary intermetallic compounds were obtained at 450℃, there are Al6 CuMg4, Al7 Cu3 Mg6, Al2 CuMg, Al5Cu6 Mg2 and Cu5Al3. |
