Fusion welding of cast high-temperature nickel alloys with high content of strengthening disperse phases is problematic. Even more serious problem is welding of intermetallic-based materials. Therefore, different methods of brazing are widely used for such materials joining. TLP-bonding (Transient Liquid Phase Bonding) is a term which has the most often application abroad. Considering that brazing filler materials have lower melting temperature than base metal the concentration of depressants (reducing brazing filler metal melting temperature) in brazed weld shall be reduced to the minimum in order to increase working temperature of brazed joints in brazing process. The depressants of high-temperature brazing filler metals are divided on several groups. Interaction of Ni3Al-based alloy with brazing filler metals containing boron, zirconium and hafnium was investigated in the work. SBM-3 brazing filler metal of Ni-Cr-Co-Al-Ti-Ta-Re-W-Mo-Hf-B system was developed based on research results. 19 Ref., 7 Fig.
