tTungsten nanoparticles of 80 nm average particle size were utilized in the brazing of 304 stainless-steels.The nanoparticles were characterized by DTA and TEM, and the brazed samples were evaluated by SEMand Vickers microhardness tests. The interaction of the tungsten nanoparticles with the metallic fillerin the melting zone modified the size and morphology of the formed phases into a finer and uniformlydistributed microstructure. In samples treated at 1200◦C for 60 min, the microhardness decreased from310 to 170 HV, being the latter value, close to that of the base metal. The nanoparticles and the microcracksdevelop a synergistic effect when they are in contact with the liquid phase in such a way that a rise inthe threshold capillary-pressure leads to the filling of the interstices. The capillary-like system resultingfrom the wettability of the nanoparticles and microcrack surfaces by the liquid phase, leads to a solidifiedmicrostructure with fine and uniform phase distribution. | |
