The isothermal section of the Dy-Cu-Pb system at 870 K was constructed. For
mation of the DyCu5-based solid solution was observed (DyCu5-xPbx, x=0-0.53
, AuBe5 structure type, space group F (4) over bar 3m, a=7.1452(2) Angstrom
at x=0.53). Formation of DyCuPb (LiGaGe structure type, space group p6(3)m
c, a=4.5585(3) Angstrom, c=7.3260(3) Angstrom) and Dy5CuPb3 (Hf5CuPb3 struc
ture type, space group P6(3)/mcm, a=9.004(2) Angstrom, c=6.570(2) Angstrom)
compounds was observed. (C) 2001 Elsevier Science B.V. All rights reserved
