采用原子比为A:Mg:Ni = 1:1:4的方法直接合成了多种新型三元镁基合金AMgNi(4)（其中A = Ca, La, Ce, Pr, Nd， Y）。用ginier - hagg x射线粉末衍射测定了晶体结构。该化合物具有立方SnMgCu4 （AuBe5型）结构，与（C-15） MgCu2结构相关。所有的原子间距离都表示金属型成键。(C) 2002 Elsevier Science B.V.版权所有
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.
