Question: ( a ) Sketch a eutectic phase diagram for a binary system A - B . Consider the idealized case of solidification with no diffusion

(a) Sketch a eutectic phase diagram for a binary system A-B. Consider the idealized case of
solidification with no diffusion in the solid and diffusional mixing in the liquid for a one-
dimensional bar and an A-rich alloy where the concentration of B is below its solubility limit
at the eutectic temperature. Draw and explain the concentration profiles of B in the partially
(50%) und fully solidified bar. (10)
