    摘要
  • 摘要: 采用Ti-28Ni（质量分数，%）钎料在1 040℃实现了TZM合金与ZrCp-W复合材料的真空钎焊连接，分析了钎焊时间对TZM合金与ZrCp-W复合材料接头界面组织及力学性能的影响.结果表明，钎焊接头的典型界面结构为TZM/Ti（s，s）/Ti2Ni/（Ti，Zr）C+W（s，s）/ZrCp-W，钎缝宽度随保温时间的延长而增大，其中Ti（s，s）层的厚度没有变化，Ti2Ni层厚度略有降低，而扩散层厚度随保温时间的延长稍有增加.当保温时间为10 min时，接头获得最大抗剪强度值120 MPa，接头断裂发生在TZM母材.
    Abstract: TZM alloy was successfully brazed to ZrCp-W composite by using Ti-28Ni(at%) eutectic alloy at 1 040℃. The effect of holding time on interfacial microstructure and properties of TZM/ZrCp-W brazed joints was studied in this paper. The typical interfacial microstructure of TZM/ZrCp-W brazed joint was TZM/Ti(s,s)/Ti2Ni/(Ti,Zr)C+W(s,s)/ZrCp-W. As holding time extended, the thickness of brazing seam increased, while each reaction layer had different changes. For Ti(s,s) layer, it stayed the same. Ti2Ni layer had a slight increase, at the same time, diffusion layer increased largely. Shear test results indicated that the highest shear strength of 120 MPa was obtained when brazing time was 10 min, and the brazed joint fractured in TZM substrate.
