Cf/SiC was successfully joined to TC4 with Ag-Cu-Ti-SiC mixed powders. Microstructures of the brazed joint were investigated by SEM, EDS and XRD. The mechanical properties of the brazed joints were measured by mechanical testing machine. The results showed that the performed joints have dense bonding layers reinforced by residual SiC and reaction products from reaction of SiC and Ti in the bonding layers. These composite brazing layers relaxed the thermal stress of the joint effectively. These characteristics were beneficial to the joint, of which the shear strengths were remarkably higher than the optimal shear strengths of the joint brazed with Ag-Cu-Ti.
