The Mg-Si phase diagram in [Massalski2] has been well established experimentally according to the evaluation of [1984Nay].
Thermodynamic assessment of this system was attempted by [1997Feu] and [2000Yan]. The calculated phase diagrams of both [1997Feu] and [2000Yan] agreed well with numerous experimental data points. However, [2004Kev] noticed that the thermodynamic models used by [1997Feu] and [2000Yan] generated unrealistic liquid miscibility gaps at high temperatures.
Figure 1 shows the Mg-Si phase diagram calculated by [2004Kev] using a revised thermodynamic model. The problems of [1997Feu] and [2000Yan] were alleviated in this phase diagram. Figure 2 shows the Mg-rich side of Fig. 1 in detail.
