“…The silver-based filler metals can be used to join a wide variety of ferrous and non-ferrous metals such as lowcarbon steels, high-temperature nickel-based alloys and copper-based alloys, etc., with the exception of aluminum and magnesium [1][2][3]. Additionally, silver-based filler metals also play an increasing role in the joining of metal/ceramic [4,5] and ceramic/ceramic [6,7].…”

The copper brazed joints were obtained by induction brazing using in-situ synthetic high Sn content silver filler metals with different B contents and the effect of element B on the wettability of filler metals and microstructure and mechanical properties of the joints were studied. With the addition of element B, the spreading area of the filler metals on the copper increases. The microstructure of the joints mainly consists of silver-based solid solution and copper-based solid solution, and the distribution of silver-based solid solution in the brazing seam becomes dispersed with the addition of B. The width of the brazing seam increases significantly with the increase in B content. Meanwhile, the B element was mainly distributed in the Ag-based solid solution. The tensile strength firstly increased and then sharply decreased with B added. The maximum average tensile strength of 206.83 MPa was obtained with a 2% addition of B and the joint fracture pattern is a brittle fracture.
