摘要：

A number of new ternary magnesium based alloys AMgNi(4) (where A = Ca, La, Ce, Pr, Nd, and Y) have been synthesized by direct combination of the elements in the atomic ratio A:Mg:Ni = 1:1:4. The crystal structures were determined by Guinier-Hagg X-ray powder diffraction. The compounds have a cubic SnMgCu4 (AuBe5 type) structure, which is related to the (C-15) MgCu2 structure. All interatomic distances indicate metallic-type bonding. (C) 2002 Elsevier Science B.V. All rights reserved.
