[Massalski 2]中的Mg-Gd相图是从[88 Nay]重新绘制的。在该图中，Mg固相线、（~ Gd）/（13 Gd）+ MgGd和（~ Gd）+（txGd）/（txGd）边界是推测性的。根据[91 Oka]，邻近化合物的液相线曲率不能有很大差异。因此，在[88 Nay]相图中Mg_2Gd的液相线显得过于平坦，这些问题在[92 Cac]计算的Mg-Gd相图中得到了解决。然而，沿（Mg）固溶线和（（xGd）/（txGd）+ MgGd晶界的计算结果与实验数据沿着不一致。因此，图1所示的Mg-Gd相图是通过组合[88 Nay]和[92 Cac]的适当部分绘制的。
The Mg-Gd phase diagram in [Massalski2] was redrawn from [88Nay]. In this diagram, the Mg solidus,([~ Gd)/(13Gd)+ MgGd, and (~ Gd)+(txGd)/(txGd) boundaries were speculative. According to [91Oka], the liquidus curvatures of neighboring compounds cannot be very different. Hence, the liquidus of Mg2Gd appeared to be too flat in the diagram of [88Nay].These problems are eliminated in the Mg-Gd phase diagram calculated by [92Cac]. However, the calculated boundaries were not in good agreement with experimental data along the (Mg) solvus and ((xGd)/(txGd)+ MgGd boundaries. Therefore, the Mg-Gd phase diagram shown in Fig. 1 is drawn by combining appropriate portions of [88Nay] and [92Cac].
