NdMgNi4 phase formation of Mg added amount of research line. From the phase diagram analysis, the preparation of the sample composition a far cry from NdMgNi4 point in the NdMgNi4, NdNi2 and NdNi3 the formation of three**phase region. When adding the actual coefficient of Mg, when a = 1.01, XRD graph contains NdMgNh and NdNi2 phase lines. With the added factor of population increase,uggs outlet (http://www.uggs**nederland**outlets.com), XRD is illustrated as a single composition point of becoming more and more NdMgNh phase composition point,abercrombie düsseldorf (http://www.abercrombiedusseldorf.com), as shown in Figure 2, c, d below. When adding factor B = 1.05, the rays from the XRD patterns obtained on the ideal NdMgNi single**phase, as shown in Figure 2 and Figure 3 shows the e. And when to add the actual coefficient of Mg B = 1.06, the diffraction pattern is a MgNi2 phase diffraction lines, the preparation of the composition points in the NdMgNi4 and MgNi2 constitute two**phase region,uggs nederland (http://www.uggs**nederland**outlets.com), as shown in Figure 2 f. 8 = 1.07, the point in the preparation of a composition NdMg**Ni4,abercrombie dublin (http://www.abercrombiedublin.com), MgNi2 and Mg2Ni constitute three**phase zone, as shown in Figure 2 g. Analysis results show that when the actual added Mg coefficient p greater than 1. O5,abercrombie hamburg (http://www.abercrombiehamburg.com), the actual composition of the alloy prepared NdMgNi point of getting away from the point of compound NdMgNi single**phase constituents. 6 Metal Materials 2Mg 2005 actual figure is not the same amount of added N ~ gNh alloy XRD patterns (a) p = 1.00; (b) p = 1.01; (c) p = 1.03; (d ) p = 1.04: (e) p = 1.05; (f) P = 1.06: (g) P = 1.07Fig · 2XRDpatternsofNdMgNhalloysampleswithdifferentfactu aladditivevaluesofMg4 Conclusion Figure 3 and Figure 4 were added when the actual coefficient of 8 Mg = 1.05, ternary alloy NdMgNi4 XRD patterns and SEM images. ● iiIIlli: Figure 3Mg add the amount of actual time NdMgNi4 coefficient p = 1.05 XRD pattern of Fig · 3XRDpatternsofNdMgNi4alloysamplewithfactualadditiv ecoefficientp = 1.05 Figure 4Mg add the amount of the actual coefficient of p = 1.05 when NdMgNi4 SEM image of Fig. 4SEMimagesofNdMgNi4alloysampleswithfactualadditive coefficientp = 1.05 by XRD and SEM analysis showed that the process of sample preparation NdMgNi, when the actual dosage of Mg 1.05 times the amount of theoretical calculations,abercrombie dundrum (http://www.abercrombiedublin.com), can be ideal NdMgNi single phase. This is ideal for the preparation of NdMgNi accurate determination of single**phase and electrochemical properties of NdMg**Ni data provide a strong basis. Loss of magnesium has two main reasons, one in the milling process on magnesium bond in the ball which led to the loss; another aspect of the sintering process, due to the low melting point of magnesium (650 ℃), in high temperatures are likely to be volatile and losses, which mutate the sample composition.
