Example 3.6
يخلط معدن النحاس والفضة جيدا في شكل مسحوق ، بنسب 80 وزن / س نحاس و 20 ث / س Ag ويتم تسخينه إلى درجة حرارة أعلى بكثير من درجة حرارة
انصهار السبيكة. ثم يبرد المعدن السائل ويسمح له بالوصول إلى توازن دیناميكي حراري. أعط تكوين كل مرحلة والمقدار النسبي لكل مرحلة
Copper and silver metal are mixed thoroughly in powder form, in proportions 80 w/o Cu and 20 w/o Ag and heated to well
above the melting temperature of the alloy. The liquid metal is then cooled and allowed to reach thermodynamic equilibrium.
Give the composition of each phase and the relative amount of each phase:
a. At 1,000°C.
