The phase diagram of the Nb—Sn system is presented. In the equilibrium state three intermetallic compounds are formed: Nb3Sn, Nb6Sn5, and NbSn2. The compound Nb6Sn5 is stable over a narrow temperature range (815 to 920°) and NbSn2 is stable from 860° to room temperature. It is suggested that phase separation takes place in the liquid state and that there is a monotectic equilibrium at 960°.
