Question:
An Al-5% Cu ingot unidirectionally solidified under the conditions of no diffusion in the solid, complete diffusion in the liquid, and local equilibrium at the interface, so that the Scheil equation applies.
(a) Calculate the composition the the liquid when the ingot is 50 percent solid. What is the average composition of the solid?
(b) What is the interface temperature at this point?
(c) How much eutectic and second phase will have formed when the ingot is completely solidified?
(d) Plot the composition profile in the solidified ingot.
