| Description |
Français : Diagramme de phase liquide-solide d'un système binaire dans lequel le liquide forme une solution idéale mais les deux solides sont immiscibles. Exemple théorique : le point de fusion du composant A a été pris égal à 200 °C et son entropie molaire de fusion à 10 R ; pour B on a pris 170 °C et 10 R. Les arcs de courbe en tireté sont les prolongements métastables des deux branches du liquidus. |
