Effect of additive values of magnesium on fabrication of single phase NdMgNi4

The additive values of magnesium during the fabrication of ternary compound NdMgNi4 prepared by mechanical alloying and sintered at 1123 K for 10 h under the protection of pure argon were investigated by X-ray diffraction (XRD) analysis. XRD analysis of the as-prepared samples shows that when the Mg additive coefficient k = 1.05, the ideal NdMgNi4 single phase was observed. In addition, the causes were discussed.
