Isothermal section at 1400 °C of the Ti–Zr–Sn system

By the methods of X-ray diffraction, metallography and microprobe examinations the character of phase equilibria at 1400 °C is studied for the Ti–(Ti,Zr)5Sn3–Zr region of the Ti–Zr–Sn system. The isothermal section at 1400 °C is constructed. This is similar to the solidus surface and is characterized by two 3-phase regions: 〈βTi,Zr〉 + Ti3Sn + (Ti,Zr)5Sn3 and Ti3Sn + Ti2Sn + (Ti,Zr)5Sn3. Solubility of Sn in 〈βTi,Zr〉 solid solution is between 10 and 15 at.% Sn. Solubility of zirconium in Ti3Sn is about 12 at.%.
