Vacuum brazing niobium using the clad 50Ti-35Ni-15Nb foil
Source abstract
Abstract
Abstract Ti-35Ni-15Nb brazed Nb joint has been evaluated. The joint consists of Ti2Ni, TiNi intermetallic compounds and globular (β-Ti, Nb) particles. The existence of brittle Ti2Ni deteriorates bonding strength of the Nb/Ti-35Ni-15Nb/Nb joint. However, the amount of Ti2Ni is decreased with increasing the brazing temperature due to the Ti alloyed in globular (β-Ti, Nb) particles at higher brazing temperature. The clad Ti-35Ni-15Nb foil shows potential in brazing Nb for industrial application.
