... unskilled operators can carry out everyday manufacturing operations. The absence of flux entrapment allows more flexibility in joint design. The postbraze cleaning of the brazed part and the furnace are unnecessary. Because a whole assembly is heated, distortion of the parts can be minimized...

... and degasses the assemblies before brazing. In addition, the use of flux is usually not required, thus reducing the cleaning and flux-removal operation after the brazing operation. Many times, the negative effects of the brazing process can be eliminated or minimized by a proper postbraze heat treatment...

... 50 °C (preferably at least 100 °C) below the brazing temperature in order to prevent remelting the joint metal. It is recommended that postbrazing heat treatment be done during cooling, within the same brazing thermal cycle, because any additional thermal cycles cause a greater chance of unexpected...

... temperatures. Other high-temperature brazing filler alloys are Ti-65V (brazing temperature of 1700 °C, or 3090 °F) and V-50Mo (brazing temperature of 2257 °C, or 4095 °F). After postbraze diffusion treatment, shear test specimens failed in the parent metal when tested at 1400 °C (2550 °F). Additions...

.... It is possible to perform annealing heat treatments on diffusion brazed joints that result in the diffusion of the boron out of the brazed joint and into the base metal. The result is a brazed joint in which intermetallic phases are partially dissolved or eliminated completely ( Fig. 1 ). Diffusion heat...

The brazing temperature, which is considerably higher than those employed in heat treatment of steel, imposes limitations...
