Abstract
Vacuum brazing of TA1/304 stainless steel (SS) was systematically investigated by changing the composition of filler metal, brazing temperature and holding time. The AgCuNi (70.75Ag–28Cu-1.25Ni, wt.%) filler metal was selected to eliminate the excessive TixCuy and TixFey phases in the weld. The defect-free joint with the shear strength of 148.5 MPa was obtained under the vacuum degree of 10−4 Pa, the brazing temperature of 880 °C and the holding time of 10 min. The holding time affected the formation and distribution of Ti3Cu4 phase and the brazing temperature affected the formation of TiCu4 phase and TixFey phases, which caused the cracks at the interface between the weld and the substrates. The excessive TiCu4 phase and TixFey phases near the 304 SS substrate's side led to the transition of the shear section from the entire weld to the interface between the weld and the 304 SS substrate.
