The phase equilibria
of the Ti–Fe–Sn ternary system
were studied at 773 K in the whole concentration range using X-ray diffraction
and metallographic analyses. The Ti–Fe–Sn ternary
system at 773 K is characterized by the formation of three ternary intermetallic compounds: TiFe2Sn (MnCu2Al-type),
Ti5FeSn3 (Hf5CuSn3-type), and Ti0.4Fe0.6Sn2
(Mg2Ni-type). The existence of substitutional
solid solutions TiFe2-xSnx (up
to 5 at.% Sn) and Ti6-õFexSn5 (up to
5 at.% Fe) was observed. The limiting
composition of the Ti5FexSn3
solid solution (x = 1.0) is
considered as a distinct compound with Hf5CuSn3 structure
type.
