Solution Strengthening the Ti-6Al-4V Joints were Brazed by Ti-15Cu-15Ni and Ag-26.7Cu-4.5Ti Filler Foils

Abstract:

Using the optimal solution and aging treatment for Ti-6Al-4V brazed by Ti-15Cu-15Ni and Ag-26.7Cu-4.5Ti fillers, the average shear strengths of the lap-joint interface are improved. And the average grain sizes and the average lengths of Widmanstätten structure are significantly smaller than that of post-brazed annealing. Both fillers specimens are examined to indicate the strengthening mechanism is to homogenize the microstructure of Ti-6Al-4V joints to simultaneously enhance the strength of joint braze and substrate.
