An ingot of Al-5% Cu is directionally solidified. Assume that there is no diffusion in the solid and that there is perfect mixing in the liquid. Pure aluminum melts at 660°C. At the eutectic temperature of 548°C, the liquid composition is 33.2% Cu and the solid composition is 5.35% Cu. Assume that the liquidus and solidus are straight lines.
Calculate the composition of the liquid when the solidification is 40% complete.
**************use Scheil equation to solve*************
What is the average composition of the solid, CSav., at this point? (Make sure that 0.4CSav + 0.6CL = 5%.)
What is the liquid-solid interface temperature at this point?
How much eutectic will be formed?
