A hypothesis has been introduced that a doping by SiC nanoparticles of a binary eutectic Mo-Ni brazing filler metal may impact the mechanical properties of the formed brazed joint. It was conjectured that the microstructure of the solidified brazement would be refined via doping, thus leading to the enhancement in mechanical integrity of the joint vs. a nondoped material system. The paper provides evidence of a marked shear stress improvement with doping vs. a nondoped system. The changes in the joint's mechanical properties are attributed to this newly discovered dramatic microstructure refinement of the solidified fillers doped with SiC.
