ABSTRACT
The cellular reaction here consists of the synchronous growth of crystals of the precipitate and matrix phases into the matrix phase, wherein the growing matrix phase crystal is less supersaturated than the one into which it is growing. Usually, the synchronously growing crystals are in lamellar, i.e., pearlite-like form as illustrated in Figures 6.1 and 6.2. Typically, the cellular structure nucleates at a large-angle, disordered-type grain boundary and grows into the matrix as discrete cells.
