A new ternary compound,
Ti4.2-4.3Dy0.8-0.7Sn≲3 (t), was found in the Ti–Dy–Sn
system. It exists at an
almost constant concentration of tin (~36.5 at.%), but has a certain
homogeneity region (8.2 to 10.2 at.% Dy) due to
mutual substitution of titanium and dysprosium. The
crystal system was determined to be hexagonal with preliminary lattice
parameters à =
4.94 Å, ñ =
5.65 Å. The compound melts congruently
above 1500°Ñ and coexists with (Ti3Sn), (Dy5Sn3), (Ti2Sn), and (Ti5Sn3).
Typical view of a particle extracted
from the as-cast 52.5Ti–10Dy–37.5Sn alloy for ÒEM examinations: à) ×100000, b) ×400000.
