Abstract：
Ag nanopastes composed of Ag nanoparticles or Ag nanowires and Cu-Ag nanopastes with Cu-Ag core-shell nanowires are used as a new brazing material for Inconel (R) 718. Ag nanoparticles or Ag nanowires are further added to the core-shell paste to adjust to a eutectic composition. Microstructural analysis of the brazed joints was carried out with EDS and XRD. High bonding strength (＞ 100 MPa) was obtained with both Ag and Cu-Ag nanopastes. It was concluded that the Cu-Ag nanopastes form stronger braze joints than the BAg-8 brazing alloy as a result of Hall-Petch strengthening. It has also been concluded that the addition Ag nanoparticles or Ag nanowires to the Cu-Ag core-shell nanowire paste have a significant impact on the bonding strength and fracture of the Cu-Ag joints.
