The growth rate of pearlite, v, and the interlamellar spacing S are given by the following relation, $$v = k.\frac{1}{S}\left( {\frac{{1 - {S_c}}}{S}} \right)$$    where Sc is the critical spacing at which the growth rate is zero and k is a materials constant. The actual interlamellar spacing observed will correspond to
