Consider you have a an alloy of composition A-40%B (mol %) and
you start to cool from 1200C (intersection at this temperature:
blue line at 0.174 and orange line at 0.542) where it is 100%
liquid.
Question: Assuming Scheil solidification conditions, and a
number density of solid nuclei of 5.66x1014 /m3 , plot the
composition of a typical grain from the centre of the grain to its
perimeter. (Explain clearly the steps in your calculation and any
assumptions you make)
