- •
Composition of 42CrMo/filler reaction layer was determined to be TiC by TEM.
- •
A nanometer thin layer of TiN1−x was formed at the surface of the TiN particles.
- •
Ti in the filler diffused towards and enriched around TiN particles.
- •
Equilibrium of the TiNx with Ag–Cu–Ti as a function of Ti content was calculated.
- •
Formation mechanism of Si3N3/42CrMo joint brazed with Ag–Cu–Ti + TiNp was analyzed.
