Wide-Gap Brazing of K417G Alloy Assisted by In Situ Precipitation of M<sub>3</sub>B<sub>2</sub> Boride Particles

Wide-Gap Brazing of K417G Alloy Assisted by In Situ Precipitation of M<sub>3</sub>B<sub>2</sub> Boride Particles

In this study, K417G Ni-based superalloy with a 20-mm gap was successfully bonded at 1200 °C using powder metallurgy with a powder mixture. The results indicated that the microstructure and mechanical properties of the as-bonded alloy were highly dependent on the brazing time (15–45 min), mainly due...
