Q3 Draw the phase diagram for metals (A, B) with melting points (1180C, 1455C respectively). They are completely soluble in each other in solid stale. Follow up the cooling of alloy with 60% B: 1. Find the melting range of alloy with 20%A (start of solidification, end of solidification) 2- 2. Find the Percent, chemicals composition of liquid and solid at 1300C for alloy with 60%B 3- Draw the microstructure for alloy 30%B at room temperature.
