| 摘 要： | 利用一种典型的块体非晶成分Zr65Al25Cu27.5(摩尔分数，％)，制备成非晶条带焊接TiAl基合金，研究了焊接接头的组织结构和成分分布，并分析了钎焊过程的组织演变规律。研究结果表明，利用Zr65Al25Cu27.5非晶条带可以成功焊接TiAl基合金。焊缝区组织出现了明显的分层现象，从中部到界面区依次是先析出的Zr2Cu型和ZrCu化合物，粗大的ZrCu型化合物和Ti2Al型柱状晶。焊接母材中的Al元素向焊缝发生了扩散，在界面区形成了一层很薄的反应层。

| Abstract: | In this paper, the melt-spun ZrwAl7SCu27.5 amorphous alloy, a typical bulk metallic glass with high glass ability, was used to braze a TiAl-based alloy. The mierostructure and elements distribution have been studied. The results show that the Zr65AI7.5Cu27.5 amorphous ribbons can successfully braze the TiAl-based alloy. Layered structures appear in the brazing seam. From the middle region to the interface region of the brazing seam, the miorestures are the Zr2Cu-type and ZrCu precipitates,the coarse Zr2Cu type grains, and the Ti2Al-type columnar grains. The Al element in the substrate diffuses into the brazing seam, forming a thin reaction layer in the interface region. |
