摘要：
The phase diagram of the Dy-Ag-Sn ternary system was constructed at 870 K using data of X-ray and partially metallographic analyses. Presence of the DyAgSn starmide in the system was confirmed (ST CaIn2, SG P6(3)/mmc, a = 0.46813(2), c = 0.73433(5) nm) and two new compounds were found: Dy3Ag4Sn4 (ST Gd3Cu4Ge4, SG Immm, a = 0.45316(1), b = 0.72887(2), c = 1.51225(5) nm) and DyAgSn2 (ST Cu3Au, SG Pm-3m, a = 0.453 10(l) nm). The DyAgSn2 is a Curie-Weiss paramagnet in the temperature range 80-470 K (mu(eff) = 10.64 mu(B), theta p = -14 K). A formation of substitutional solid solutions DyAg1-xSnx and DyAg2-xSn, was established. (c) 2006 Elsevier B.V. All rights reserved.
