3. Consider the solidification of a 10-micron rod based on the alloy indicated for each student in the table below. For the given alloy, draw the solid concentration curve that will occur in the equilibrium state and Scheil solidification curve along the length of the rod. (Draw the phase diagram for the indicated alloy using Thermo- Calc software and use the necessary values from this diagram.) Al-13(wt.%)cu Solid Liquid 4. Repeat the 3rd question using Thermo-Calc software and compare the results obtained with Thermo-Calc and those found in the 3rd question. Clearly specify the Thermo-Calc procedure and include relevant diagrams and screenshots. 5. Based on the composition changes in the solid and/or liquid, draw at least 3 different representative microstructures for the alloy provided to you, considering equilibrium and Scheil solidification results (i.e. at points such as solid+liquid at high temperature, solid+liquid at lower temperature, and at room temperature). Compare these microstructures.
