| 850.15 | eutectic: L -> (Al) + (Si) + AlP | model | [1] Liang 2014 | p. 8 report | However, an extra ZPF line of the AlP phase appears, shown as the red dashed line between the liquidus and solidus line of (Al) and continuing exactly along the horizontal line at 577 °C above 7 wt.% Si. This entire horizontal line in Fig. 10a represents the cut through the ternary eutectic L ! (Al) + (Si) + AlP four-phase equilibrium. | |
| 850.15 | eutectic: L ! (Al) + (Si) + AlP | model | [1] Liang 2014 | p. 15 report | Based on this, the first consistent and experimentally supported Al-Si-P phase diagram was calculated, including details of the most important ternary eutectic, L ! (Al) + (Si) + AlP, at 577 °C. |

| Phase transition | 789.15 K | 789.15 | L -> (Al) + AlP | model | [1] Liang 2014 | p. 14 report | This ends at 516 °C, where the extended solidification path hits the metastable extension of the AlP crystallization surface. At this point the calculated residual liquid composition is 19.9 wt.% Si and 2.2 ppm P, which may be compared with Fig. 6. |
