A hypothetical binary eutectic phase diagram of A – B is shown below. An alloy with 5 wt.% B solidifies with no convection. Assuming steady state, the critical temperature gradient (in K mm-1) required to maintain planar solidification front is: ______(round off to nearest integer).
Given: Diffusivity of B in liquid = \( 10^{-9} \) m2 s-1
Velocity of solidification front = \( 4 \) \( \mu \)m s-1

The constitutional undercooling condition for a hypothetical binary alloy of A with solute B during solidification is shown in the figure along with its binary phase diagram. Based on these two schematics, one can conclude that the solute concentration in region X will be __________ the average composition of the initial liquid phase.
