Hi guys(adsbygoogle = window.adsbygoogle || []).push({});

The Scheil equation for the segregation of impurities from a liquid to the solid during solidification is

C_{s}= C_{0}K_{eff}(1 - f_{s})^(K_{eff}- 1)

C_{s}is the concentration of impurities in the solid

C_{0}is the initial impurity concentration in the liquid

K_{eff}is the effective segregation coefficient (< or = 1)

f_{s}is the mass fraction of the melt that is solidified.

I have trouble understanding what is going to happen as the solid fraction goes to 1. If anyone knows what's going on in this equation please help me out - I hate not understanding this!

Any further detail needed please let me know.
