G041024 Metallographic structure of titanium braze alloy processed by the liquid phase diffusion bonding method: Its dependency on process temperature and time

Abstract

The liquid phase diffusion bonding test of Ti-6A1-4V was performed using Ti-20Ni-20Cu-20Zr brazing alloy. The process temperature was 905, 935, 965 deg C. The hold time was 10, 60, 120 min. Metallograhic structures of bonding layer were evaluated, and needle-like structure layers were observed at all test conditions.
