Isothermal sections of the phase diagram of the
Gd–Cu–Sn ternary system were constructed at 770 K
and 670 K in the whole concentration
range using X-ray, metallographic, and differential thermal analyses. The
interaction of the components in the Gd–Cu–Sn system at 670 K results in the existence of five ternary
compounds, while at 770 K only four
intermediate phases were observed. Detailed crystal structure investigations
were performed for the GdCu5Sn (CeCu6-type) and Gd2Cu3Sn6
(Sm2Cu4Sn5-type) compounds. The existence of a
substitutional solid solution GdCu5-xSnx (up to 5 at.% Sn) was observed
at both temperatures.
