For uniaxial plane-front solidification: Binary A-B eutectic phase diagram with straight-line liquids and solidus. Tm-650 C; melting temp of pure A, TE= 500 C; eutectic temp. mL = -4%C/wt%; slope of liquidus line, k = 0.25; equilibrium partition ratio, co-5.0wt%B; solute concentration. For non-equilibrium solidification, use the school equation to calculate: (a). the composition of the solid at the interface, the composition of the liquid, and the temperature of the interface when solidification is 75% complete. (b). the average composition of the solid, and the average comp of the liquid when solidification if 75% complete.
