| 摘 要： | 采用Ti-15Cu-15Ni钎料对TiAl基合金与42CrMo钢进行真空钎焊连接.利用扫描电镜、能谱等分析方法研究TiAl/42CrMo钢接头的组织及成分分布.结果表明,TiAl/42CrMo钢接头中分别在TiAl基合金母材和42CrMo钢附近形成过渡反应层区,钎缝中出现Ti-Al,Ti-Cu(Ni),Ti-Fe等相.简单阐述接头的形成机理.

| Abstract: | Ti-15Cu-15Ni was chosen as filler metal for TiAl/42CrMo steel vaccum brazing.The Microstructure and composition distribution of TiAl/42CrMo steel were examined by SEM and EDS.The results showed that the transitional interaction layer was formed at the interface close to TiAl and 42CrMo steel because of interdiffusion and interaction between the filler metal and the base metals.Ti-Al,Ti-Cu(Ni) and Ti-Fe were formed in TiAl/42CrMo steel joint.The bonding mechanism was discussed. |
