Abstract
Cf–SiC composite was brazed to Ti alloy using an interlayer of Ag–Cu–Ti alloy, Ti and C mixed powder. Microstructure and shear strengths of the brazed joint at both room temperature and 500°C were investigated. The performed joints have dense bonding layers reinforced by in situ synthesised TiCx from reaction of C and Ti in the bonding layers. In situ synthesised TiCx provides good reinforcement and alleviation of the joint thermal stress, resulting in an increase in strengths of brazed joints at both room temperature and elevated temperature.
