Tungsten nanoparticles of 80nm 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 SEM and Vickers microhardness tests. The interaction of the tungsten nanoparticles with the metallic filler in the melting zone modified the size and morphology of the formed phases into a finer and...
