Abstract: The active brazing filler metal AgCuTi was successfully employed to achieve the brazing connection between carbon fiber reinforced silicon carbide (SiC_f/SiC) composite material and GH4169 nickel-based superalloy. The study investigated the influence of brazing temperature on the microstructure and mechanical properties of the joint interface, and analyzed the bonding mechanism. The typical interface structure of the joint is GH4169//(Ni,Cu)-Ti//Cu(s,s)+Ag(s,s)//TiC//SiC_f/SiC. The phase composition of the microstructure remains essentially unchanged with increasing brazing temperature. Under the brazing condition of 860°C/10 min, the room temperature shear strength of the joint reaches a maximum of 64 MPa. Shear fracture occurs at the brazing seam and the interface with the SiC_f/SiC composite.
