GLY 4200 Homework Exercise 4 Binary Phase Diagrams - Solid Solution Behavior 1. On the first diagram, outline the liquidus in green , the solidus in brown . 2. Trace the behavior of the melt at A as it cools from 1950°C to 1400°C. Show the path followed by the liquid in red , and by the solid in blue on the first attached diagram. At what temperature do the first crystals appear? 1840°C What is the composition of the first crystals? Fo 97 At what temperature is the liquid entirely converted to the solid? 1600°C What is the composition of the final liquid phase? Fo 38 What is the composition of the liquid phase at 1700°C? Fo 52 What is the composition of the solid at 1700°C? Fo 90 3. On the second diagram trace the behavior of composition B as it is heated from 1320°C to 1800°C.
