Mechanical properties of nanoparticles reinforced Mo-Ni braze for a dispenser cathode application
The mechanical properties of nanoparticles (either Mo-Ni or SiC) reinforced Mo-Ni brazes were studied by microindentation. It was noticed that: (i) for MoNi near-eutectic fillers doped with 3% and composed of 100% Mo-Ni nanoparticles the non-eutectic phase features consistently a larger hardness than the eutectic phase. Fillers with various additions of Mo-Ni nanoparticles respond differently to the indentation. An appearance of cracks hasn't been noticed in this case. (ii) for Mo-Ni near-eutectic fillers doped with 1%, 3% and 5% SiC nanoparticles, two phases with different hardness are identified as phases I and II. Cracks still exist in all cases with the addition of SiC nanoparticles.
